MIT grad introduces logs and shows how to evaluate them. To skip ahead: 1) For how to understand and evaluate BASIC LOGS, skip to time 0:52. 2) For how to evaluate weirder logs, including the log of 0, 1, a FRACTION, or a NEGATIVE number, skip to time 6:44. 3) For NATURAL LOGS (LN X), skip to time 11:17. 4) For even weirder logs, including SOLVING for X and using the CHANGE-OF-BASE formula, skip to time 14:56. Nancy formerly of MathBFF explains the steps.

1) BASIC LOGS: you can read log notation as "log, base 3, of 9 equals X". The small (subscript) number is called the base. You can always evaluate a log expression by rearranging it into something called exponential form. Every log expression is connected to an exponential expression. In this example, the log is connected to the exponential form "3 to the X power equals 9". This means, "3 raised to what power gives you 9?" Since 3 raised to the power of 2 equals 9, the answer for X is 2. This is also the answer for the value of the log expression. The log is always equal to the power (or exponent) in the exponential version, and in this case it equals 2. If you want, you can find the log value in your head just by asking yourself what power you need in order to turn the base number into the middle number ("argument" number). Note: if there is no base number in the log expression (no little subscript number), then the base is 10, since 10 is the default base.

2) WEIRDER LOGS (log of 0, 1, a negative number, or a fraction): you can use the same steps to rearrange log expressions that have a fraction, negative number, 0, or 1 in them. You can still rearrange them to be in exponential form just like you can with the basic logs from earlier. The log of 1 will always be 0, since 0 is the only power that can turn a base into 1. The log of 0 will always be undefined, since no power can turn a base into 0. The log of a negative number is undefined in the real number system, since no real power can turn a positive base into a negative number.

3) NATURAL LOGS (ln x): the natural log is just a special type of log where the base is e (the special math constant e, which is approximately 2.718 if you plug it into your calculator). You can use the same steps for rearranging the log expression into exponential form. Just remember that ln x means log, base e.

4) EVEN WEIRDER LOGS (solving for X, change-of-base formula): even if there is an X variable in the log part of an equation, you can still rearrange the equation into exponential form. This will let you solve for X. Sometimes you might need to use the change-of-base formula to evaluate a log expression. If there is no whole number power you know that works, it may actually be a decimal power that you can find by using the change-of-base formula. For example, you can re-write log, base 2, of 7 as (log 7)/(log 2) and use your calculator to find the decimal number if you need it.

Hello my queen

Julian Mungarro Let me guess with an IQ of about 83 math is not your strong point.

Pathetic.

Julian Mungarro fedora in your profile pic perfectly complements your comment

@Jeffrey JeffreyFLF How are they a perverts by just saying that she is a queen? Come on bro.

don’t sue me for defending a man..

This comment killed me 😂😂😂

She’s a peasant not a queen

Can you make videos about linear algebra and more difficult calculus? That would be great!

AnimePianoAngel really would love to see that

Beautiful Nancy 😍

@nancypi could you do a video on laplace transform, Fourier series and differentiation. Thanks

LMAO thought you said “lapdance transform”!

Nice video nancy

Hey nancy really love your videos! Greeting from Ecuador

Very nice 🙂

I literally have an exam in a few hours with this topic lol

Same Here 😀 😀 Final Exam xD

nakanokana I have a test on this in 20 minutes

The Blue Recruit okay me 😭😭😭

Same

That’s me

Awesome!! Thank you for this. You’re excellent at explaining

Hey nancy ,i thought you abandoned channel ?? can you pls upload videos more frequently !?

can you make a whole video on probability…. my frns and i realky need it.

It will be very thank full. Thanx Nancy.💓

my ques is whats your daily routine, and how to be good at maths..by what to do everyday

do math everyday, I did 6 hours of maths 5 days a week for the last year and I improved , by How much it

s subjective.

I like your smile and thank you

how are you writing like that. cuz i think you are writing right to left. what is going on

I think she has a glass black or white board.

There’s a pool of mercury on the floor that the camera points to. That reflects off of a concave mirror on the ceiling which then focuses the light into an optical spectrometer. At this point the individual wavelengths of light are broken up into their corresponding quanta and rerouted through a dimensional polarity amplifier using a coherent phase emitter.

All of this is then recorded on twelve 1.44MB floppy disks using a harmonic neutrino field array. Tetryon ion injectors then transfer the data to a base modulator, which, of course, is uploaded to youtube.

Of course, that could only be it. How about string theory? Where would that fit in. I bet you a subscription to Penthouse that it will fit in somewhere. The big question will then be will the end of the universe happen as a freeze up or a melt down?

aND A COUPLE OF CAMERAS AND A GREEN SCREEN AND AN EDITING DECK.

Nice!

Nice video Nancy. Thanks

It’s okay Nancy. I like both Maths and your video.

Thank you

Mathematics- vectors please

²

YES Please

vectors are really not complicated, you cold just get a maths book

there’s a great computer graphics book which explains this

I’m on summer vacation and I’m still watching.

Was goodie brothers why we doing this is too learn pre calc or calculus

NERDS!!

@2017 Was cancer ur nme 😆

Eww

@Latina K hi

No doubt you are the best your explanations are mind blowing…

Hi Nancy, I am so glad that you addressed log in this video. When I reviewed logarithms I did wonder why logarithms of ” any base” raised to infinity cannot be treated as equaling ” zero?” I have not reviewed calculus yet, but I do seem to recall that was the way expressions and real numbers were treated to evaluate them for their derivative. Would this not be logical?

I have no idea how you can reach this conclusion. A log of any base raised to infinity: ( log(5) )^inf. <=> inf*log(5) = inf. this is pretty straight forward. Now if you mean: log(inf) = zero. OR the limit ( as y -> +inf ) of Log(y) which is = +inf. Maybe I don’t understand your question.

I thought ln was used for solving indicies

Can you teach geometry? And if you guys have a good source to share with me to learn geometry, it would be great.

Check out the website mathisfun, just google it, it has A LOT of things including geometry and it’s free.

I have seen this stuff somewhere berore 40 years ago. I wonder ??? I am weird but ddon’t know why you need these? It is interesting now though.

I am apparently an Aspie. I seem to be able to work these out in my head. Am I using the force?

James Parlane these aren’t too complicated. I’d say you were normal using a little brain power.

I’m only here for the ASMR.

Was this Babich guy just a trouble maker?

Sorry, Babbage?

Thank you, Nancy! This is so helpful. Please keep on being such a blessing!

There’s a new branch of Mathematics, to be called Humane Mathematics! 😉

Is she writing backwards?

That’s why I want to know!

The fact that logs never go to zero should scrape your degenerate minds out of the negatives to realize the absolute truth of the Riemann Zeta function.

Leave Nance alone you filthy animals.

thanks loads of fun

haha, said no one ever!

How write 😌😌

Good video but I was really hoping to learn how to calculate the less tidy logs like log(7). Thanks for the video.

1:25 “more power to you”

I see what you did there.

x^5=32 has 5 distinct solutions… x=2 is only the most simple.

Please sir, explain other four

@Senpai The other four solutions are complex numbers. Write x = r exp(i phi), so x^5 = r^5 exp(5 i phi) = 32. Solution requires exp(5 i phi) be a real positive number, which only happens when (5 i phi) is an integer multiple of 2pi. So the five solutions are: 2, 2exp(i 2pi/5), 2exp(i 4pi/5), 2exp(i 6pi/5), and 2exp(i 8pi/5).

about damn time we get some vids……………………..<3

I find it oddly sad that basic math teaches log defaults to base 10, and yet programs like Mathematic and R use e as the default base for log. Who really cares about base 10 anyway?

Very nice presentation. You probably could have said that

ln e = 1

log 10 = 1

log base b of ( b ) = 1

Anyway, very nice presentation, indeed. Keep up with good and valuable videos!

e=2.718 it is not equal to 1 as it is known as Euler’s constant

Can u make vedios on applications of derivative. (AOD)

Hmm…I’m getting dejavú or was this already a video made by you?

Hi Nancy! I just graduated as a Electronics & Communications Engineering. Thank you for saving me from my college days.

But Romans go home is an order is’nt it boy? So you must use the?????? Imperitive.

Can u pls do videos on integrations…

can i see your set up, i want to start doing this for my 8th graders. Thanks for the easy videos for them.

nice work again Nancy, thank you, what about some different bases like 1 , 0 or a negative one?

very gd miss perfrct. ur explaination jst awsn..

im 4rm india n i wanna meet u once

Sister Nacypi Is Wilson is your another YouTube account.

@NancyPi – Love your channel and have been following since mathbff, could you please do a video explaining Newtons Method?

Why are you so pretty?

Thanks for teaching me Logarithms.

Nancy,We know that

10^2=100

Then, Log 100=2

2=Logarithm of 100 to base 10.

Isn’t it easy?

Nancy,try to include the following formulas to your next video.

Log (A*B)=?

Log(A/B)=?

Log A^n=?

Please teach me.

Thanks

can you do more videos about calculus? love ya

I just found the new channel. Perfect timing because I start calc 1 on Monday.

Nice to see u nancy you look skinny

Shiiiit! Gorgeous

I remember trying to solve logs back in highschool and just not grasping them. This explains the process so well! Nice work Nancy!

Nancy, ln (-1) = pi * i, where i = sqrt(-1)

I know that the ln funciton is really undefined for negative numbers, but if it’s okay to say that the infinite sum of all positive integers is -1/12, then NancyPi needs to have her own untrue, but popular, fact.

An equivalent statement is e^i*Pi = -1 . Of course, one should note the periodic nature in this result.

As a matter of fact, it was once believed log(-x) = log(x) from the fact multiplying LHS and RHS by 2 gives log(x^2).

Euler was the first to give the result that ln(-1)= PI*i

Students learning at this level don’t come across that quite yet hence why she stated log(-x) is undefined.

Its also useful to understand that b^x > 0 (b>0) (for real x) hence log(-x) is undefined for real numbers.

Euler was the first to connect logarithms with exponential’s. Roger cotes knew that ix = ln(cos(x) + isin(x)) but missed its periodic nature.

At 9:26 you say that any number raised to 0 equals 1. How is that possible? Why wouldn’t it equal 0? Since 2^2 is two times itself=4, and 2^3 is two times itself three times =8, wouldn’t it follow that 2^0, being two times itself 0 times, =0?

Grover Smittle 2^0 doesnt mean 2 x 0

@Fufu-Trap ! yeah it’s actually non-sensical 2^1 is 2, 2^2 is 2*2 is 4, 2^3 is 2^2^2 is 8

we know that x^a / x^b = x^a-b,

x^a / x^a =1

3/3 = 1

so what if i wrote x^3 / x^3, it would be equal to one also the if we subtract the powers we get

x^0=1, hope this helps

I like to think that by decreasing an exponent by one divides the power by the base. 3^2/3^1=3^1 3^1/3^1=3^0=1

I quit bff for you, Nancy, you the real mvp

Hey ! I understood the entire idea, but why does it help when dealing with questions like 3^x =9 without using a calculator (for a lot more complicated questions)

I mean if you simplify 9 it becomes 3^x=3^2 so you know for it to be true x=2. You don’t need a calculator to simplify 9…

@Sheren Lin I think he meant general application of log. One application is when you have gamma function ratios involving an integer n, and you want to take n outside so you know how many for how many n you reach a certain bound. f(n) < C(n). Then you can use Stirling approximation to express n in simpler function involving log than gamma function.

Certain things are us logs such as decibels. So they have an application. Richter scale also uses logarithms.

Ever notice how the identities of addition and multiplication are shown in log1 =0 ? Can’t have the log of 0 or anything less.

Food for thought.

Nancy, That is really helpful. Easy and thought provoking lecture.

The hardest part for me was do I want to look at you or your examples!!!

LOL

What do u do when u have log√x

just started college thanks for the video it really helped and wasnt boring

The one Nancy did for… Log base 2 of (1/8) …can also be done using the Change of Base Formula …she shows in the last example.

How do you find a logarithm of a fraction with a numerator that is greater than 1

Hey Nancy, could you do a video on logarithmic differentiation. I love your videos by the way.

Damn girl, nice brain.

Thank you for making my life easier 🙂

thankkkk youuuuu!!! you should teach my math teacher how to teach

Thank you for saving me 😄🤗

thanks nancy, you are the best 🙂

Thank you so much Nancy! Great well structured video

Nice like it

🙏✝️

New subscriber😍😍

I assume this means that for any and all lne^y =x; x = y.

love yaaaaaaaaaaaaaaaaaaaaaaaaaa

you made me fall in love with LOG-Rythmez. nothing weirds not even the weirder. 😀

did u write backwards to make this video i donut understand

I am 40 and I’ve gone back to Uni, your videos are really helping me, you’re awesome.

hi mam! thaks for excellent artship in teaching

They didn’t teach us some of these things properly in class. We have exams tomorrow too :<

Very nice teaching !

This was very informative and just what i needed! Thank you so much! If you can do video requests, could you do a video on Matrices???

Beautiful. Thanks!

How can I study if I got such a hot teacher like u can’t get my eyes off from u😍😘

ty Nancy 🙂

Could you please do a video on Statistics (standard deviations)

wow amazing!!

omg, how do you write like that? also, good video!

U really look gorgeous😍

Thx . Exams tomorrow

Please do SIMPLE AND COMPOUND INTEREST. please 😢😢😥. You’re awesome 💕

Is anyone else extremely confused as to how she is writing while looking at us without the letters being inverted?

And what is that, an invisible board?

I’m so confused, but it looks cool.

Thanks for this great tutorial 🙂 Just wanted to point out that the fifth root step was missing in the example given at 16:17 of the tutorial for the following example:

logx(32) = 5

x to power 5 = 32

5√32 = 2

x=2

Where were you 40 years ago when I was in high school?

Süper.

Logarithms… Who cares? (NancyPi 😍😍)

Im glued to the screen

lass what happens if you have a fraction infront, (1/2) log3 36 – log3 2

your voice is very convincing……. I like the way you explain

Are you an introvert????? You don’t sound cheerful……cheer up

NANCYYYYY

Smooth way of asking for a LIKE lol

ممتاز جدا

من اي بلد انتم

How does she write on the screen, is she mirror writing?

NancyPi: Making maths beautiful again. Great teacher too.

*Looking gorgeous*

Fantastic explanation

babe

عفية عليچ حلوة وذكية

Thank you for helping me pass my classes!

You explain in very well manners it’s too good and learning with you without doubt increase more concentration , since u r too cute

the backwards writing mirror or video flip thing makes this hard to watch as its very distracting.

All Meant to Keep us Distracted from the Truth .

No one will absent his class if a teacher like yu teaches. You are beautiful by knowledge and by face too

So what kind of math is this? I need to learn more math.

Nancy could you do a video on financial arithmetic

surreal…how she writes

Jennifer Connelly’s younger sister.

You are hot, if you are my teacher I will be listening to you all night long.

watching high energy people do math stresses me TF out. Nancy is so chill that it’s actually a little relaxing.

These had been bugging me for a while but I understand now. Very helpful video, thank you Nancy!

Thank you Nancy 🙂

You saved my life with this video! Thanks 1000x

how come that she writes the opposite side of us and still manage to write all of this without even a spelling mistake?!

She writes backwards better than I write forwards

well done mate

thank you so much Nancy.God bless you.u really saved me .i now understand the concept better

Hi Nancy.. I find it very hard to follow as yu explain.. can yu get a bit uglier😊😊 so I can’t focus less on yu..

You remind me of Aubrey Plaza. Thank you, great explanations.

You’re very clear on how to explain things. Really understood it better after watching your video compared to teachers that love to teach so fast.

D.a couldnt focused lmao

Thanks a lot, hi from Italy 🇮🇹

I love you’re explanations

YOU ARE THE BEST

Great explanations! But natural log is represented as ln and not nl .. ??

your cuteness makes learning very difficult. i like that.

Logs and ln made me quit maths when I was young. Thank you so much for that. You really deserve that like. I am so happy right now! Thank you very much, Nancy! 🙂

They simply should not be taught to school children. Kids are covering far too much mathematics and are then leaving school with no foundation in mathematics.

She’s pretty.

You r beautiful

Thank you!

Can someone just give me the answer for 2x(squaredplus2)=16 help me

she looks like the nun from nacho libre

*cue nacho voice*

“enCARnaCIOOooooOOOOoooOON”

YOur hot you seriously graduated from MIT are you single? The stuff that your teaching I learned it without a teacher in 1 sec by using a calculus book

Damn, 3D pens nowadays surely has a sky rocketed update

sorry i couldnt pay attention <3

Snail-log-natural= garden

Yes Nancy!!! So easy to understand!! God bless you!

She is so good at drawing backwards 😮

You are too cool

You saved my life! I have a test this wk and I was having a hard time grasping these concepts.

Thank you!!! 💕

Hi

Which software do you use for the video, specifically the mirror one.

Thanks

I liked your video before i watched it!

Great video but if you could only speed up by a bit, your videos would be much better

Thank you. Are you writing backwards?

Can someone help me with ln W^5=t ??? Please?

Thank you so much Nancy!

How does this marker board work?

I like your approach. And I think some of the comments here, show that you’re having a real, positive effect.

If I might, I’d like to offer a few minor, constructive (I hope) criticisms.

Around 4½ min: “log” without an index automatically means base 10; common log?

Actually, in a fair number of places, it means base e; natural log. I think your viewers need to be made aware of that.

Around 11 min: log(–1), undefined.

Good for the basics; but it might be good to hint that this becomes possible later, when we find a new kind of number that we’re not going to go into right now. This sparks some interest, by creating a little mystery – the curious will start asking questions and doing some searches, and who knows what might come of that?

At the end: log₂7 = log7/log2.

You didn’t show the value; the decimal.

That’s a good thing!!

Once again, there will be some who are curious enough to go try this, to see what they get.

Fred

I love you

A.shakur Ahmed She is older than 10.

never mind logs I’m still trying to figure out how you write backwards.

You make math sexy

Do you write backwards?

Yes , but what practical purpose do they have apart from giving students a headache ?

Absolutely nothing mister their fucking us over everyday, your lucky you missed the wave

Oh f***, its Nancy 🙌❤

thanks. Enjoyed your clear method of explanation the snail thing is helpful too. Time to watch your next video on solving Logs.

How long did you have to practice to where you could write backwards like that? Do you think writing like that could give you dyslexia? I heard that De Vinci wrote like that.

she’s writing normally with her right hand then flipping the video

Oh, really, wow. For a while there, I thought that she was really pulling off a great stunt. Thanks for straightening me out.

am I the only one that notices you write all of it mirrored-ly (backwards to appear to us as normal????)

Awesome teaching

way better than the khan academy bits that ive seen about logs

I now have a reason to care about logs.

11:50 natural logs

cool refresher, i had forgotten all the details

If she had been my Trig teacher in high school I would have had a crush on her and flunked.

Hablo español y estoy viendo esto lol

Practicando inglés (? haha

Silvia Guerrero Jajaja Que inteligente . Asi después que aprendas inglés puedes aprender la mathematica. Pero el inglés es mi primer idioma y no entiendo ni papas

Not to distract u or anything but if u slow it down to .5 speed she sounds like a stoner and it’s hilarious ok bye

Lifesaver 😭😭😭

I’ve been just using the log rules all these years without noticing this. The log and exponentiation notation has always seemed weird to me. I wish I’d known this 30 years ago. Also, I’m super impressed by your ability to write backwards so neatly!

You know…..she’s right handed.

Quite a skill… to mirror like this.

Did you train it or did you have it… out of the blue?

What I want to know is how long it took you to learn how to read and write in a mirror image like that?

You know the instructor is a pro when he/she does pronounce ln as lun!

Nice.i like you Nancy

Educational to say the least.

I am totally nerding out. I love listening to you. So organized and everything you are saying makes perfect sense.

You mentioned that a log without a base is automatically 10 so if we have something like this:log 50 will the base still be 10?

yes it would be

Can you demonstrate for me please😢😢I am kinda struggling

Arghhhh!!! Cannot focus!! She is so beautiful!!! 😂😂😂

Thanks, Nancy – very nice explanations, and a great methodology for solving these problems.

You might want to discuss where logs came from, and how they were originally used (as a way to approximately carry out large multiplications via addition).

Also, your approach and answers are true for the Real numbers (lots of other interesting answers for log(-8) when Imaginaries, quaternions, or octonions are involved 🙂

Wait.. Are you writing in reverse?

is this done with video effects, or are you writing backwards on a piece of plexiglass in front of you?

Thank you so much really helpful also i cant help but notice how beautiful you are

Are you actually writing backward on a transparent board?

Never in my life did I wish for a math problem to be more complex than it is. A lot more. Ahh well.

very nice explanation ! :-b

Lefties who can write backwards are so hot!

I wish the Nuns teaching me back in the dark ages thought so, instead of hitting me with a ruler. Ah the good ole days…..:-)

I’m glad somebody else noticed this. Watching her write on the glass has been blowing my mind.

What’s even more amazing, is she’s writing it backwards to it looks forwards to us! 🙂

So perfect…

Thank you so much for your hard work and clear and concise explanations.

You are a life saver.

Consider that everything she is writing from her perspective is “backward” as she is on the back side of the clear pane.

Gives you a small indication of just how brilliant she is.

She is writing normally, the video is flipped left/right.

Thank you for making all this easy to understand. It makes self study possible.

You manage to smile while you do math

I love how you thoroughly explained each example!!!! AWESOME!!!!

Beautiful armpits. I wonder how they smell. Can I sniff?

I’ll be a sexist dick and say “I’d love to show her my log rhythm.” 😀

Nothing sexier than a smart lady who’s attractive. <3

?sdrawkcab gnitirw ehs sI – Is she writing backwards?

This was the best title

I’m over 40 and never understood logarithms. Now, thanks to you, I do. Thank you for the fantastic explanation. You’ve taught an old dog a new trick!

what is the purpose of logs?

Maths must now be PC those patriarchal inspires Logarithms.

Awesome teacher, quality instructions and a very very cool name (NancyPi) ! Subscribed.

Awesome job explaining, the snail analogy is great! Also I’m impressed how easily you wrote everything backwards.

Great explanation 👍🏻

Everybody’s commenting on the math or how pretty she is… I’m over here trying to figure out how the heck she learned to write backwards so well!

I know how she does it, but I’m sworn to secrecy.

Its cuz of the camera

@Shamin you made my day man

And i am thinking how is she writing in different colours with same pen

RIGHT?!! That really stood out to me.

She’s good at writing backwards.

Ok stupid question, is she writing backwards on the glass?

Nancy, this was sooooooooo helpful! I have a better understanding of logs now! Thanks for your video!

makes me crave milk…..

I shall call you by your roman name – ” Smarticus ” … never could get what the heck logs and for that matter calculus was used for except to give small children headaches.

You deserve way more subscribers

I’m fuc**n inlove!!!

So the natural log is LN. That’s the other way around?

So either Nancy can write fluidly in reverse, or she’s really right handed.

It was clever of you to go ahead and write on the glass and then flip the image afterward.

Gosh, If I had a math teacher like this I’d have gone to M.I.T.

Just wonderful to see someone with brains and looks and sparkling personality as well as a gifted instructor. Just great.

Hello math Goddess.

Holy moly guacomole

2!

how long did it take you to be able to write backward?

2:00 WHAT THE HELL IS THIS!?

3:00 Hey, you’re a Lefty. So am I. Did you know that the number of left to right handed people is reversed for monkeys?

So what are Logarithms?

I saw no logarithms.

I spent a significant amount of time alone in my bedroom studying these!

if you can graduate from MIT, you can write backwards… where do people use logs in real life?

beautiful!

Wow math sure has my full attention, now

I think it’s quite important that if you’re going to deliver a lecture on Log E that you can actually show an understanding of and articulate what E is.

Lipstick looks and red chalk? How is this allowed in the 21st Century?

Nancirooskey, I think that your kinder and gentler than Khan, and therefore you may very well transform the collective consciousness towards “a thousand points of light” in mathematical terms. Not sure exactly how to log that.

Can do something like 1/3 log 27 – log (3^3 -18). How can I do simple questions like that I get confused

Why do we need to know this about logs?

Very nice job, Nancy. Well done.

Very nice idea to write this way.

But why do you speed up while writing? Looks unnatural.

Now the real question is how much is log[3+4i]2i ? log of 2i using base 3+4i …

log -1 = i*pi

Suggest to also add the following to your video:

e ^ ln x = x

log (x*y) = log x + log y

log x^y = y*logx

Didn’t know math can be so beautiful

but what is 2 + 2?

22

Marry me Nancy. Maybe you’ll heve more time teaching me. 🙂

Very well done. Excellent progression of skill-layering. Obviously Nancy would make a fantastic teacher, but I get the impression she is way beyond that. It would have been nice to end the video with a very practical example; Like using logs to calculate pressure in a hose, or a graph of the housing market, acceleration, etc..

Never watch the mathmatics, But her.

i’m here for beauty

wow, she is pretty woman

How are you writing backwards, yet I’m seeing it forward? That’s the real question.

Some people write “log” with no explicit base for natural log.

Freaking gorgeous and smart.

I thought shes d soloist from d ‘Corrs’?!

plz whatsapp me +923369769880 plzzzzz

😒

OMG am struggle to consecrate on the real subject of this video.

good looking

Where were you and Youtube back in 1990 when I needed this? This is great math explanation and cool post production effect. Thanks,

I know math,but she brought me here

Never thought I would enjoy Logarithms so much.

I have my Math final coming up. This vid really helped a lot, thank you 🤙🏽

Who else is watching the video for not knowing Logarithms!😂😂

Thanks a lot for this! I think I finally got logs!

you made that topic easier..i was struggling in school before

Well explained. Thank you. Nancy, you’re so young and you have a great future ahead of you whatever you do. Keep up the good work!

I have a big log in my shorts watching you

Very good👍

hi Nancy3,14

why not all teachers are like you

🤤

damn, sexy teacher !

more youtube vids like this and we eliminate lady gaga.

i see u still didnt reach 100000 views….that says a lot.

u have my support.

Do you actually write it backwards? This must be a camera trick sorry if I’m late to the party

How a great way of making videos, congratulations !!! Not to mention that the exposition is clear, simple, easy to follow. THANK YOU A LOT !!

look at her hand, is she a gamer?

How strange you write ?

Not for nothing but HOLY SHIT – she is smart

Why am I watching this

Hey your videos are absolutely amazing, thank you! Could you please the logic behind the change of base formula? I want to know why it works :D.

Thank you again your videos have been a massive help to me.

You work pretty fast, are you human? I like the explanations. Thanks

What’s the purpose of logarithms?

Thanks Nancy.

Advanced Merry Christmas.

God bless, Proverbs 31

ادرسو من علم عباقره العرب 😎😎😎

log(-1) is undefined only in real, but not in complex numbers. -1 is e^(i*pi), so log(-1)=i*pi/ln(10)

Babyy😏😏😏

Yum .. 😉

I am pleased she is “NancyPi” and not “NancyTau”. 😉

Really conveys almost no mathematical competence. Having “patterns” to deal with logarithms is not very useful from a mathematical point of view, because you have no framework, no concept to guide your application of the logarithm or to understand other people’s application. The mechanics of logarithms are well explained, though.

Wow, high school was so different.

NIce, I got them all from my head before you answered. Math confidence is a good feeling.

May you be successful. Thank you for helping mankind evolve with so much passion in what you do.

In fact, from the point of view of the programming, when you say “log” you refer to the natural logarithm “ln”, therefore it would always be necessary to verify to which base it refers.

Nancy, how can you write inside out? you write in the perspective of the audience from back…. and you are lefty…it’s mindblowing what you are doing on this video.

2:00 How do you do that? Writing backwards, being pretty and doing math in the same time… How do you do that?

That’s the first time in my 38 years when I finally understood how logs work. Clear and exact explanation! Wonderful job!

what kind of cake does this make?

Please do tutorial for quaternion and octonion please…!

Just crushed from space and watched this video. And it enlightmented my brain with logings 😛

i think everrything is fine .. but you just need to edit a little bit your video to make this more attractive and organized. and yeah… expressions and expertise will come with time. Best of luck.

Smart and pretty. Mommy…….. So above my intellect and pay grade unfortunately. So wish it wasn’t true. Hey you like dummies? I’m your guy!!! Hit me up LOL. The upside would be you get almost everything past me and I’d be like duuuhhhhh (drool) ok! Thats a positive you don’t find everyday ahahahahaha.

12:05 What is e btw? It is “JUST” a special number in math.

Ha

Ha

Ha

A lefty 🤗

I like math, I subscribed for obvious reasons.

Top marks for explaining, plus top marks for writing backwards = top marks squared.

sometimes log(x) assumes the natural base (like in programming languages), so one must be careful. It’s better to ask the base if you’re not sure.

Thank you Nancy!!! but i’d like to know for what do we need to use it?

Why is this so easy? I never understood that in school. Great video! Thank you 🙏

Awesome! Liked the video and it even came back after 15 years. Wow! I love math!!! It’s so simple and beautiful when it’s worked out.

heh, trudno się skupić na liczeniu

you have the best audio on youtube. great mic great voice. you are also pretty organized and elegant in how you teach. excellent channel. subbed.

I’ve probably had close to a hundred teachers from all the years at University – if she were one of them and it was a class I had to pass; I wouldn’t have made it… How do you choose to look at Math when someone so beautiful is right there beside the Math to look at instead?

Damned if I wouldn’t be in the front row every class, appearing to be paying attention, even participating and asking questions; still, I guarantee every Test, an F. I probably wouldn’t even write anything down on my exam; I’d just be hypnotized…

It’d be awkward the first go through the class; but if it were required, the 4th or 5th attempt to pass and it’d be really really awkward. I’d sit and stare; she would pity my apparent retardation yet still have to fail me again and again.

I’d eventually wind up sobbing every night knowing I’ll never get through the class and go forward with my studies; she would eventually wind up sobbing every night feeling guilty having to fail someone seemingly low-functioning retarded time after time.

I dodged a bullet though. The Math I had to take, all the Professors might as well have been leprous monsters by comparison…

😍🤤 maaaaaaaaaaath 💞💗💘

I don’t study well with a hot teacher…. 😜

Sod the LOGS! She was writing in reverse. Now thats impressive 😂

I wish my Maths teacher was as hot

For around 18:50, why don’t you just put the value of log 2(7) directly into the calculator function: log (number) rather than log 7/log 2?

In fact log of 0 gives minus infinite, you can know it by plotting the function. Of course calculators do not manage this case.

For change of base formula, keep in mind logₐ(a)=1

I don’t believe You.

Why pink?

Q. Basic log: you should show us how to find x. Your demonstration assumes we already know solution, does it not.

that actually basic math that you learn about logarithms around 14-15year old and btw u can calculate the logarithm of a negative number u just have to use ί

you are very hot, you learned to write in mirror mode?

Made my life so complicated with the ( ln (e^3) ) problem why didn’t you just write x=3 Jesus Christ, you are pretty cool so ill let pass.

💓

She’s the new Log Lady.

Great Vid

My life is getting better when I study English by repeating school courses math.

I was learning Binary Trees. From there i came across logs. Once i come here, i paused watching and read all comments about how she writes backwards. Had to mirror my monitor screen to calm myself from the mystery. Clever and Engaging!

First of all thanks for your labor Nancy. But i cant understand, is this subject is hard to understand? In Turkey, this is a highschool lecture and no one struggles for understanding. I mean it is an easy subject i think, because your lecture is very basic level and of course you are a great teacher according to this lecturing but this matter is not worth for such easy explanation according to my humble opinion. Every graduated highschool kid can solve easily without listening such basic level explanations of this matter. But again i think you are a great example for how a teacher must looked like. Thanks for all your efforts.

When she was teaching even weirder logs I told “that’s a freakin mess” a total of 7 times.

I understood it later, well taught.

Are you really writing backwards?

Logs for negative numbers are undefined in real numbers. You can get a complex answer, though.

logs…emmm

Ядрена пасатижа

И так хер пойму эти логарифмы, так еще и на англицком базарят

Ну нахер

NancyPi, you are an AWESOME instructor! Your methods has made these concepts a lot easier to me. Thank you, and what’s the name of the software program or apparatus that you’re using, that enables your marker to appear on your video upload? Thanks in advance, and PLEASE keep the tutorials coming.

you make maths simple

Thank you, finally got it.

Proved: Check @3:26 “and x = 2” her hand makes a thick mark at the ending of writing 2 due to its pressure on the glass and then the shot is taken again to make it look seamless. Also the video switches between pink and black marker seamlessly. It’s all good video editing and smart production to make it look like Magic. More power to them.

It’s a Simple glass in front of her with the camera facing towards the glass. So she is writing with her right hand normally and the camera is recording it. After the complete production the movie is flipped.

Hello my Queen !

The thirst is real in this comment section

People who do this useless meaningless math must have (0) life!

A^n = A^m iff n = m

Negative logs are possible through polar calculations!

Log base 10 of -1 can be written as ln(-1)/ln(10). According to euler’s identity, e^(ipi)=-1 so ln(-1)=i*pi. So log base 10 of -1 is just (i*pi)/ln(10).

@Dawn Ripper this is math in the real number line, not the complex plane.

@N1cKyP4mH4zP0Pc0rnT0Eat What a coincidence, I just saw you commenting on Blackpenredpen’s weird chinese post!

No se ni puta Madre de ingles mucho menos de matematicas pero estas chulisima niña y por eso voy a aprender

HEY NANCY … THANK YOU VERY MUCH I LEARNED LOGARITHMS FOR THE FIRST TIME AND I REALLY LIKE THIS EFFECTIVE VIDEO , BEST OF LUCK 🙂

I remember initially learning about exponents and that they consist of a base and a power… and Logs also have a base.. so I found it easy to remember that the base of a log is also the base in the exponential form

i understand clearly especially the weirder ones and how too solve problems with fractions without overthinking many thanks.

I love your video about linear systems

Well, she does name the video How, so I can’t say anything, but I need the Why. Why logs? Why do they exist?

Thank you Nancy

Be nice if mathematicians would explaain what these equations are trying to accomplish. for instance, what does a log do in the real world”?

Is she writing that backwards or is she right handed and they just sideways inverted the picture?

I can’t stop thinking about it…

BareSphereMass I was initially thinking the first option but if you look at the partioning of her hair in the video and then compare that with her dp and qna video then it seems like the second option is true and the video is inverted.

I wish my math teacher taught us this way in high school. This is the benefit of Internet. I am so jealous of those who are in high school now.

Yes, teacher

very nice

Please help me understand is she writing on glass or is there any other trick I’m missing out on?

I found this video by accident, I guess? I have been watching random math related videos here and there and stumbled upon this. At first I thought, “Wow. Logarithms are so outside my my capacity.” But after watching you do them I was was overwhelmed by how easy they are. So I just spent the last hour on Khan Academy learning logs and doing practice examples! lmao YAY MATH!

Any medical students in 2019??😂😂😂

O.G LOC first year here

Cute AND smart

I’ve never, ever, thought that ‘logarithm’ sounds pretentious. Weird.

😍

You are great at explaining! This saved me! Thanks.

I would have enjoyed math more in school if you were my teacher.

how she writing backwards so well

Is this girl white?

Tell me who is here only for mam…….

She writes BACKWARDS!! Oh Yeah, the math is good too!

lol watch in 0.25 speed

Hi Nancy. Will you marry me?

Where were you when I was trying to learn this?? I know…. Your Great-Grandparents hadn’t met yet. That’s why I was do bad at math!

Are u writing backwards?

Cant I do that on a scientific calculator?

Thanks Nancy you are awesome you helped me a lot

What’s answer comes by dividing log 7 with log 2 ?

My 11th grade math teacher said “If you remember nothing else from this course, you WILL remember that a logarithm is an EXPONENT!” Thanks, Mr. Branson. It has been 40 years, and I still remember.

Note: in some advanced (and probably older) math books, log without the base means that it’s a natural logarithm (base e), NOT a common logarithm (base 10). Watch out for that!

Exactly, Ken. See my post.

> I would keep you…

Beautiful! (pun intended)

I may have missed what a log is and why you’d have to solve them. Did I miss that?

A power is a based raised to an exponent. E.g. 10^3 is the 3rd power of 10. When you use the word power you really should be using the word exponent.

thnxs

What the hell….stick to the easy way…..your over complicating the whole thing…….are you on the enterprise?

Are you really writing backwards ? Mindblown

Thanks for the nice explanations !! You awesome !!

Kindly tell me which kind of glass board u r using? I have tried but the color is not so bright out! Thanks in advance!

Very appreciative method but i wonder is what a technique to write on crystal like screen ! Amazing !

You are very good in teaching and you are also much pretty and beautiful.

maybe start with “what is the purpose or use of “logs””!

you are too pretty I’m totally distracted xD

Logs can burn in hell

555

For me you are too attractive to focus. Sorry. Have good day.

I always admired hot maths teachers and thats how, I excelled in maths as lot of attention was paid to her details.

Thanks this was really helpful 🙂

I had to study these in college years ago but nobody made it as easy as you did. Oh yeah, you are pretty aren’t you? Thanks.

I Log you

Okay youtube I’ll watch this recommended video of a pretty girl who explains math by writing backwards ! *sighs*

I can’t solve your logs but you can solve my log, oh yeah yeah

“how do you evaluate it?”, “what if you have to simplfy that?” are all questions that come after “what is it?”, “does it have a value?”… and then you start with “make it equal to x” and a series of convoluted instructions with circles and arrows without clearly stating what you are trying to do. After two minutes “btw this is the base”. Then you call that thing exponential, but you should call it just power. This is why people don’t get math. Math is not a series of recipes. There are a handful of fundamental concepts and then everything follows just using logic, not snails.

Hey there pretty

Amazing. I could just leave all my stuff here, go to wherever you live and become your husband and support your math teaching. Lovely. Hope to see more.

It’s fine and all but is missing the whole key to logs and that’s why that function exists and is used. Would’ve been nice if you showed a plot of the log function, where it appears in nature, finance, engineering, etc.

Natural Logarithms functions are inverse of exponential functions. Shall we go on?…

You are actually quite good at teaching math.I can actually understand you.You talk at a rate which is easy to follow.

Your my favorite math teacher.

It would be useful to first know why. As in why are logarithms useful and what are they used for?

are u a left-handed?

Nice…

Love this channel. OMG! Love this Channel. This channel is a godsend

Thanks for this brief and well explained resume of logs!

It’s also good to illustrate the log functions (I liked your snail analogy, though it doesn’t explain the appearance of the functions :)) to ease the understanding how logarithmic functions work and why there can’t be negative logs

How you do that? On the glass? You can write backwards?

This is the problem I have with you mathematicians. Maybe start by explaining what the hell is a logarithm and how the hell is it even a thing that is even useful. Like I was thinking some time ago how the hell did they get the relationship between pi and the square of the radius of a circle gives us the area. What the hell is pi anyway and why the square and not the cube or whatever. Then I stumbled across a video where a guy explains this exact thing and it made perfect sense which anybody can fully get. So maybe do something like that and tell us what the hell is a logarithm and why is it useful. Thanks.

Everytime you mention X I think of your ex. Poor guy 🙁

My heart’s on fire. FOR MATHS!

I didn’t knew this kind of magic…

Damn I dont see a ring XD Some guys gonna be real lucky smarts and beauty with a lovely smile

Like and subscribe for the beautiful lady 😀

This is great thank you so much! @NancyPi

Good explanation. I wonder how many young male students were able to concentrate on that?

So smart and so beautiful, i felt in love

Thank you for this, it’s a big help.

Any one noticed! How could she write in backwards?

So the first basic log is basicly the same as saying 3 x 3 = 9

Holy hell *LOL* called it, I’ve been watching this for 2 minutes and 30 seconds.

You are great

Log e.

I wish you’d been my uni math lecturer: that was easy to understand – he made it impenetrable! (I mean you now. I doubt you were even born then! ;p)

She’s writing from her right to her left

Well this is new content for ASMR

This . . . . this is how I’ll learn math.

Remember to always flush your logs when you are done. Sorry, I know, I can’t believe I just said this. Now I will walk away in shame 🙁

Great teaching!

This is too weird

log of a negative number is a complex number. Not undefined.

I’m wondering why I’m watching this, my mathematics knowledge is way higher than that.

Thanks for the snail technique!! Have a test tomorrow on this and this vid really helped

I tried the snail technique but wish there was something faster.

Thx Nancy very much cozaa its tragedy for me without yr vid 👏👏👏👏

You wrote backwards 0_o

Why not jut.put 3×3=9. ..simple

I love the pink colour of the marker

all math teacher should look like her

Wow, You can write backwards. and with the left hand.

The video speed up when she write. But in real time it’s slow writing…

It’s true that any number to the power of 0 is 1, however it essentially means the base dividing by itself. Speaking of division, there is a restriction which is dividing by 0. Therefore, the base also cannot be 0 because 0^0 = 0/0 = undefined (or also known as “indeterminate form”).

I like this Nancy………all math teachers should be like this.

gosh can any man alive concentrate on the math in front of her???

Çok güzel ve değişik bir yöntemle anlatıyor 👍🏽👏🏽

If I had a teacher like this, my attendance will be 100%

SAME. I’ll absolutely get straight A’s too. Damn

Hahahaha… @ ZWheel1 — Same here. That actually blew me away the way that works. Magic, for sure! But she is also a beauty… with brains… I dig that.

OK… this is driving me crazy — how does your writing software / video thingy work???? So fascinating.

U r very beautiful

why I learn this ?

So women who do math don’t pout, do filters, tattoo eyebrows or attention seek. Intelligent women any day.

Cool video

She makes me wanna learn good.

apart from showing of how smart you think you are…whot posable use is this CRAP im 69 and have never been asked to do this crap

so we watch the video to watch the woman?

The real value of the first 1000 significant decimal places of Pi are as follows:

3.1446055110296931442782343433718357180924882313508929506596078804047281904892436548476515566340325422595160489765784452235018414818847721014580011238453531659969963123944614330895602447224013851373131501976513250168886718624703787313359434961827623424884419929696155384972370055738355223468907453641698014204369640943817463269453772663395414398903709747924249157889297802333906441767084172268827515380592173997026423023851194242244081992685573437499657987944611238911016107551387207358281657572181883283516336139159023992353694690024845170044516992781985453761660350519720800718970644071409668757828437246633219026822340025407725353821526637922670369853908547616452436921953232107331044735525949802311653660216067204763773809792592558234876801085351187469338952701406443781568048374310664077223404139952343917185562861066240175976669357645765480751311418697916950736513185281927426366978973484884146736468201663051035828968367940082442276210780785802770252790792921943126282608098219773061432750203769…

Pi = 4/sqrt((1+sqrt(5))/2)

This is the only value for Pi that harmonizes the area and the perimeter for circles and squares, making them equivalent to each other and fulfilling the universal law of conservation of mass during a geometric transformation!

TURKEY

Thank you Nancy, I love how you explain mathematical topics. I love even more your natural beauty, stunningly beautiful :))

Oh dear, if only I’d had such a beautiful sweet teacher when I was a teenager … I would have done anything to understand, have good marks and please you … Instead I was a total zero and hated math ! By the way : first time in my life that I understand logarithms, are you a magician ? Unfortunately I have neither time nor space in my adult life for math … so thanks and by 😉

*My eyes keep on looking at her.*

She’s pretty/nice…

😁😁

The reason she learned how to write backwards/mirrored, so that people dont stare down her ass while she teaches math.. Very clever.. Now pay attention 😂

Me too

@GRIZZLEE haha she doens´t write backwards, she write normal in a mirror, when she is editing the video she apply mirrored effect, and looks like that…

Damn it, How am I gonna learn?

because all I can Focus on is “NANCY”.

You’re totally right and I’m not even lesbian.

@Lara Perez AHAHAHAHHAHA DAYUM!

ya got that right!

@Lara Perez you can become lesbian if u are in love with PI

Marry me and teach me the maths. I need to get learned.

Very good…..thank you.

Brains and looks…Marry me!

No

@vestigial code Shut up!

π no es la relación perímetro diámetro pues una circunferencia no es un polígono regular es una curva cerrada

Is she writing on camera screen?

No, she does magic

Ummm. Probably

she’s clearly sitting behind a panel of glass on the off chance you’re not being serious lol… The crazy part is I think she’s writing it backwards?

She probably wrote normally on a glass panel and flipped the video through post-editing.

I passed my maths college exam but watch these videos because of her

Just landed thank you

wow your explanation was amazing and i didnt know anything about logs although my major is mathematics in iran university but now you learnt me alot of things thank you so mush

Saw the thumbnail and just knew the comments were gonna be fun to read

Holy F#@%! how do you write backwards so well??!!

good vid too

Yes

What… I watched the whole video i didn’t know it was about math.

😂

Thank you Nancy for sharing your knowledge to the world. May God bless you!

a cute maths teacher

why we need to take log of any number? why???

Nancy please marry me.

I love her

I Ike pie.

I believe everything you say.

😂😂😂😂😂

lol

This man deserve a 💓

Bro that’s how it works in real life also 😂

S i m p

Why youtube recommend me this. I don’t like math. My search pattern in a lifetime don’t include word math. Youtube is broken big time.

other reasons 😉

great. thanks

*I don’t see any logarithms*

Wow, she is so pretty

I start to love math

Does she teach private tuition?? 😋

Were they invented in Logar, lol thats the province I was born in 😀

The real question is…. How does she write backwards on a glass between camera and her…

Suddenly, I like maths !

Thank you. Neat and sharp 👏🏼👏🏼👏🏼

Wow smart and pretty 😃

A Woman who is Attractive and is Intelligent is Great Thing to Behold!!

She is not left-handed.

Math’s will be easier if all the teachers teach us the way you teach with humbleness and cuteness . BTW i love this video , thanks

she is writing backwards with left hand and talking about some math. imposible

Nancy is hot

I think logarithms are pretty funny:)You should try tri algorithms like tri rapide.

Your fans miss you, when are you posting more content?

u look damn gorgeous mam

I wish i had a math teacher like her when i was in high school. Man would i pay attention

😧

what are we talking about here this vid is going to hit 5 million. hmmm what if she was actually simulated still how could it be possible for one to focus on the subject matter.

There are no women like this in my life. And I am sad because of it.

So we have seen the logarithmic analogue of 6-2=x, 6-x=4 and x–2=4. We can treat these subtractions as abstract grammatical “rewrite” subjects, or make them more relevant (i.e. understandable, relatable or teachable) with real world examples. Your move, ms. MIT graduate …

I’m in love.

Pretty, smart, excellent explainer, can write backwards. You make me love math 😂

The math is beautiful

Man, this math is fabulous..just fabulous.

all i see here is those beautiful smiles and the glamorous face that best explain the logarithm.

Thanks for the help

Calculus next

Omg…

ez math == ez life

Beauty and intelligence in the same person. What a rare combination.

As a retired electroengineer i finally understand the basis of logaritms.

Adorkable…

Nancey i like you!!!!!

Hi nancy.ur teaching is too good.

Come for the math, stay for the sudden crushing sense of voice dysphoria lol. Seriously tho this video REALLY helped me with my math!!! I am a marketing student who is AWFUL at math but this was super clear and easy to understand!!!! Thanks!!!!!

I got a 71 on my midterm😑

I have passed multiple university math exams and know all about logarithms, but I didn’t mind the explanation at all, I watched all of it for some reason, hmmm.

I am in love, but not with math 🙂

your smile wao

Man I wish my teacher math is like her…. I will received math understanding much faster. never really able to do logarithm till this point in my life…. already graduated school about 20 years ago.

I’m in 2nd year electrical engineering, I would say that I’m very good with logarithms. I clicked on this video, just to check out this pretty lady!!!!!!!

Nancy U r extremely smart woman and I can’t help but notice that U were trying to control Ur laughter & ended up smiling throughout the video😁😂🤣

Sound effects when U write fast are really funny 😂😁

And of course U r absolutely gorgeous with a lovely soothing voice. Wish U a very happy valentine’s day 😍💞💓🌹💞

If U were teaching this in a classroom, there won’t be a single vacant seat.😁👍

Excellent video. 👏👏👏👏✌😂👍

Ставь лайк, если не смотрел в правую сторону))

Con una maestra así nunca falto a clases.

Gorgeous + Smart = Perfect 🙂

….. I love you

Great! Thank you very much.

Even though I’m a math student in the 7th semester I couldn’t stop watching the whole video… There are rumors it wasn’t because of the math in the video…

Nevertheless the video is very well done regarding it’s actual purpose!

log2 7 I not understand how to solve it please explain why did you divide it

thank you

are you really writing backwards?!

Aşık oldum

biz Turkiye de bunlarin kralini ogreniyoruz

Correct me if I’m wrong would log base 2 of 7 be 1 over log base 7 of 2

Hi Nancy can you please make a video in surds…?

Thank you mam. Good teaching.

I really like the visual of the glass writing screen.

I regret at times I was going to school there was no YouTube!

if she was my math teacher, who knew i could have ended up being anything

Any ideas on how to solve this question,

In triangle ABC, AC= 18cm, angle ABC= 60 degrees and sinA= 1/3

Use the sine rule to show that BC= 4 root 3

Mathway.com

Muhammad Fahad thank you!

Thanks so much.

thanks you are awesome

I am pk boy and I should meet you for mathematics

U fuckin saved my life I failed my ged now I passed caused yo videos for a week🥳🤯👏🏼👏🏼👏🏼🙌🏼🙌🏼🙏🏼✍🏼✍🏼✍🏼

I literally was struggling with logs, but , your explanation made it very clear and much easier to me.

Omfg, that ending was smooth as hell! Here take my like!

thank you so much!!

Log2 7 = 2^2^1.75

228,453 views but none of them learnt a bit, i am pretty sure

HOT

This is so easy how tf did I not get it in class 🗿, thank u Nancy 😔✊🏼

Not so good

great

This woman is amazing.

thank you

Please keep posting. You’re great

thanx Nancy u r very smarter

Yeah…but you’re not very good at math nor writing, so let’s move along to the next comment

@Why-not-DIY i really love this! thanx very much NancyPe

If you be my techer 😍3 years ago, then i definetly crack the exam 🤩😍of Ams

This woman could tell me to kill my family and I would do it.

We’re not related are we?

Hey “nancypi”, you clearly try too hard to look all cute and stuff. Just be yourself. Nonetheless, Great video!

How to calculate the log starting from 0 point(.) Eg-log 0.741

How to watch the video.

Hanım ablam sayende artık matematiği seviyorum arigatou

I to like the presentation.please may you show me how to tuckle logs of unequal base ok

I cannot seriously concentrate.

Damn! She explained it so well

I know how she do it. She mirrored the video.

Where were her camescope while teaching please?

omg dude you are so right, anyways whats your opinion of israel?

I wish i cud have a teacher like her

You remind me of the woman from good will hunting that will ends up dating. 😂 you guys could be twins or something. Haha

Can somebody be so beautiful and be good at math?

She gives me ASMR

I can’t concentrate, she’s to pretty XD

But why?

Never thought I’d see the day I learned logs in 19 minutes

I’m about to watch the video while I could be watching GTA. But it’s only because she does a good job at explaining everything plus this is what I’m currently doing in precalc 2

Making logs is much easier.

@halfhumanhalfzombie “Making logs is much easier. ” as long as you’re not constipated.

@Harry Ross Exactly, that’s my sarcasm XD!

a wee bit

I’m in love with the way she processes the stuff to write things like this in her mind ……

I know log very well but I’m here because of just for u pretty nancy

Yup same here😁

19 minutes gone as 19 second, because she and her explain are pretty nice 😍

You are a great help, or your explanation is.

god damn… I totally forgot that I click on this video to learn math…

Thanks for such explanation .

I don’t understand a single shit but I’m still watching

It really helped me

Thank u

How the hell are you writing backwards better than I can forwards?

she is writing on a mirror with her right hand!

@Remi Schmitt ?

Thank you so much Nancy! I was so confused before I watched your video.

You’re the reason why I actually like math

Thank you Nancy; you are an awesome teacher. God bless you, Nancy.

Q. 3^2 – log base 3(4×log36)

Literally here trynna study for SAT test tomorrow lmao gotta get that good score sis

K. Kevin .K omg same good luck king

Pls let study change of subject

if she was my math teacher I would never fall asleep in class.

@Alex Kim Don’t tell me. You’re gay, right?

Terry LaRue no wayyyy

@Economics and Business studies For you chutiya

@Surendra Singh you are

@Alex Kim someone has a crush on someone hahahaha

Hahah. Backward writing. Lv it. And god Math can be so hot … 🙆♂️ … where were u when I was in schooooool …

I am student of math honours… On first day of college I find no female student studied math…. Girls help to learn math are exceptional, I am amazed

Islamic culture hinders women.

Me gusta ti pizarron magico 😀

hot

THANK YOU!!!

Thanks Nancy no one has ever explained Logarithms so clearly and easy! thanks so much!!!

she is pretty isn’t she

Beautiful and smart go incredible together… 🤭

Nancy saves the day once again!

Nancy π (3.14159265395) ; birth day tuesday(3), fourteenth (14) january (1) year 592 B.C. she has 65395 friends.

Nancy please tell me true or false ! tan(you) love tan (I) ballance sin (both) / cos (you), cos (I)

A lecture, which was delivered very well. Noteworthy is that the lecturer made the effort to face her audience, which grabbed my attention and motivated me to pay careful attention. This was a nice rehearsal for me, thank you.

I commend her for doing this. With her look, she could probably be a more popular Youtuber doing pointless reaction videos or any other crap things most kids watch these days. But instead, she decided to teach us maths. God bless her. And whoever you fall in love with, lady, he (or she) must be a very lucky person to have you.

Thank you for the great videos!

Does she use LIPSTICK for Explaining, why did I just have male teachers in my life, how I got my life wasted in that way ?

Dark knight, those are regular dry erase markers.

She is smart.

I suddenly started being interested in logarithms

Suddenly Im interested in logarithms

Thanks NancyPi

🖤😔

I didn’t understand anything because I was confused in her beauty

Good for you

Wolf in sheeps clothing…😂

Thanks Nancy! You’re videos help out a lot!

love you

I will Explain everything about how my girl write in this way…..The way of the people thinking is not right…My girl does not write in a mirror way ….. In her most videos We saw that she write with her lift hand but in the video of (Nancy answers your Questions) you will find that she welcomes us with her right hand not with her lift one as in the most of her videos….The way is she writes with her right hand in a glass then she mirrored the video itself…..My girl is not a super girl… She is a smart one♥

❤

Its like someone plugged me into the Matrix….”I understand Logs now!”

Your lesson is good for new English adopter, I need the knowledge basic idiom. You are beautiful, and your lesson is good for the new English adopter for their accumulation of the words in mathematics. The lessons are filling the blank,and increased the possibility of the diversity. Thank you for the effort!

Thanks Nancy for describing it in a such a beautiful way that I’ll never forget it.

Avikalp you are a true man of romance

I really had a test today morning and after giving it I can score much better in it

💐💐Hi Nancy You Looking Too Much Pretty and Your Study Way Pretty Like You.Thanks For This Knowledge.💕

💐💐Thanks About Logarithm

Where’s her ring?

Beauty n brains….nice! go find a good man babe…marry n have kids to pass them good genes on to.

Thank you Nancy. Nice and clear.

Es la primera vez que veo tu video, y me he inscrito de inmediato. Lo veo muy atractivo una mujer guapa que domine los cálculos. Eres sabor doble Nancy…

If she was my teacher I’d have 100% attendance..

Very sexy madam

Anuj Chauhan lanat

Anuj Chauhan youre super ugly

I’d attend extra classes too

@Anuj Chauhan inappropriate

how was this filmed ?

Nancy u r the best teacher in the world. I love ur teaching.

Cute cute

Nancy you are the bomb girl!

I really like you 😍

A good teacher do not 100% make a good student. A hot teacher : yes

Love her

why log and its use in daily life

Fell in love with math all over again

your too beautiful, it’s illegal for you to teach math.

true.

I wanted to see the cute math chick…dropping logs.

that’s y I love you Nancy , you always get me out of my misery … Thank you so much

Talented

You’re genious

I think you don’t using your left arm, you using mirror effect.

Math is a very easy to understand but need to update (Practice),otherwise very difficult to revise.

how the hell did you write backwards o.o

Nancy , you are so great ! thanks alot

Like for this video…. ll subscribe when u post more on weird logs

Cutie pie suits u……

Can u make video on Fourier transform ?

I will never be able to learn logarithms from NancyPi; my biorhythms keep getting in the way…

aFreeman0409 😀😀

I’m dead!!

@Omari Lewis

You must be – if you can watch this beautiful woman and still think straight…

I love you teacher nanse

pleasant voice and shy smile

Hey Nancy, great video but maybe you should have explained what e is. It helps to demystify this magical e. Yes its a number, but I’m guessing that’s confused people to what its used for and where it came from – or a link maybe. Also, it’s also worth pointing out the Ln is the opposite of e. So in your example for ln(e^3), you didn’t have to do anything at all since one is the inverse and they cancel to 3 Sort of like taking the square root of a squared power – after you showed your workings of course.

Honestly all these thirsty comments are disgusting. She’s not a sexual object to satisfy your gross desires, she’s a teacher so instead of thirsting over her why don’t u actually listen to her as a teacher and not as an object

You can distracting.

to be honest, i am favorite of logarithm, but you are!

Most soothing voice EVER!

thank you for this simple explanation! I am struggling in my online math class and this is a HUGE help, 🙂

Enjoy dude!

I don’t know if I’m here for her or the math. Dang, If I had teachers this pretty I’d be a pretty smart guy.. 🙂

Can you read it as log 9 base 3?

wow

yes she is gorgeous BUT did I miss where she defines a logarithm

just typed into Bing…log10(-1) = 1.36437635i not a real number …if you like you could say you broke out of real numbers into the complex planeC

imagine 100 dollars in various banks for a year all running the accounst differently

. if the compound interest is added more often ,proportionately, you get more cash .e is the multiplier you get in the limit as the pennies get added more and more often.

e=(1+1/n ) ^n

n goes to infinity

I like math. Math is beautiful.

I am so distracted by your beauty

I am loving it

You’re beautiful, sexy and smart. We love you Nancy !

I appreciate your teaching method !

Never thought math could be so beautiful. Now, I’m in love with math. Thank you!

She seem so excited when she said you can like my video🤧

Asu estas chulisima, preciosa, mua!!!

suddenly im intersted in math

Very Lucid explanation. Even a middle school child can understand it. Good and keep it up, Nancy

wait, is she writing backwards?

Forget all come i learn u new math from old persian empire civiltion IRAN 3/6/9

Hi Airo, It is fascinating to find somebody who is interested in Old Person Civilization. I thought after the Arab Conquest the Persians were made to entirely give up their heritage and take up the ways of their Foreign Overlords. It amazes me today, that Iranians (the direct descendants of the Noble Persians), whose Arch Enemies are the Arabs still cling to the Arab Religion that was foisted on them due to their unfortunate defeat, when their Original Religion, Zoroastrianism, was the FIRST Religion of the Book and Zarathustra the FIRST Prophet of the FIRST Moral Religion.

just finished my final-

Thank you so much, I’ve been beaten up by math but then your video saved my life

why am i watching this , i am not even math student.

i love 😍 love 😍 love 😍 love 😍 love 😍 love 😍 love 😍 love 😍 love 😍 love 😍 you nancy pi the way you teach is average but you are looking awesome awesome lovely

log e^x=? plz rpl

Hiii,I am from india ,I really understand

Clearly I need to go back to school. I got lost at “log”.

u r so beautiful

NancyPi? More like Cutey Pie.

Very helpful. Thank you.

Thanks so much for the explanation,I never had an idea of what (ln) stands for.just left blank spaces on my exam paper

She has a real gift writing backwards, WOW!

Salam aleykom , peace with you.

I was flipping with special effects until I realized that you wrote with your left hand, ha ha ha ha.

Congratulations for your videos and your system, it’s really brilliant.

u r still flipped tho

Marry me?

Thank you Nancy. This is beautiful lecture. Thank you very much.

i dont see any log, i see a beautiful tree 😉

Hi Nancy

Could you show ratio and proportions and K constant please?

Thanks

Super

This helped me so much thank you

I know logarithms pretty well and I have nothing to do with maths anymore. but still I watched this video just because of you ❤️

Very helpfull, thank you!

Great and simple explanation! Thank you for helping me revise the logarithms!

Where were you when I was in college, you would make my life less miserable. Thanks for the videos

Your mobile no mam please take me

@NancyPi correction log(0)= -∞ as far as I remember from university.Also, log(-1) is also defined log(-1)= (i π)/ln(10).

I’m also curious where does log= log10 coming from. I was always using log x(y) as generic, lg=log 10(y), ln=log e(x). Has something changed in notation?

It depends on which discipline you’re in. In general, “log” means log base 10, but I have also seen it defined as log base 2 or even on occasion log base e. I would just avoid using it without a base. It mostly gets used for “whichever log we use the most”.

Best explanation thank you maam

Not one video with sleeves. It must be hot in your studio there.

I love maths. That’s why i am here i swear.

Ok , but better on 1.25 speed for me.

AmaZing! Thank you for such a simplified way of explaining this.

Very good explanation. Subscribe to us the Lozadas, I love math!!!

Man, why do guys become stupid when a good looking woman speak, I’m a dude myself, but when I want to jerk off, I watch porn and when I want to learn something I go on YouTube and LISTEN to what the person says…. Why don’t you guys don’t give her more credit for the smart things she says instead of just her looks, her DNA, it’s so sad, not being able to look at intelligence and see how beautiful a smart dialogue is, seeing intelligence as an inferior attribute compared to looks …. of course she uses her looks to get views, don’t fall into that trap, be smarter

Hello madam I love you

What is log used for in the real world? I bet I can find another way around this if you show me where it is used.

To measure pH, you use log.

To calculate the pH of an aqueous solution you need to know the concentration of the hydronium ion in moles per liter (molarity). The pH is then calculated using the expression:

pH = – log [H3O+].

Example: Find the pH of a 0.0025 M HCl solution. The HCl is a strong acid and is 100% ionized in water. The hydronium ion concentration is 0.0025 M. Thus:

pH = – log (0.0025) = – ( – 2.60) = 2.60

I just came for the fawning wankers who could only comment on her appearance and not the subject matter. I was not disappointed.

I’ve been suffering learning this easy concept, but you’ve planted into my mind. The book is very confusing as well as the teacher; both were so stupid! Your way is so easy. Thanks so much!

I wish my maths teacher was this hot

I don’t understand till now how they right like that🤔🤔😨😱

Your so gorgeous and brainy. Thanks for the info

I have a question that says

Use common logarithms or natural logarithms and a calculator to evaluate to four decimal places.

Evaluate the expression:

Log pi 68 is aprox what

How on earth do I put that in my calculator lol. Do I input log 68 / log (pi) ? Please

Using a Ti-30x IIs . We are required to only use these in the testing center 🙄

Hii iam from india , be friend

This is m’y phone nimber :

***********

How many of us watched the whole video and then realize that we have no connection with mathematics and watched the video just because of her.

Am I the only one who’s very attracted to her? Wow.. if only you were my tutor 🙂

Algebra and calculus were torture for me. This seems easier to understand but I need an example of real life use of this knowledge…

Saludos

I can’t even concentrate. What did she say in this video?

although I have no idea what I have to do with “logs” youtube recommended me it. I just Watched it anyway.

guh

博士，其實畫图博士的图，从计算程式功式为基，而例如像斜缐支力点和受力点以及压力点不同，而延伸，大约数(以前博士以符号標示)，而精细数以符号加根号加倍数或減，，，，，，，，，—直如此習慣，，，SO，大约知者为妻妾子女徒或是，，，死人才知，而且死很久很久，，，SD??。

she’s too cute. 😍

In the first minutes I thought she was highlighting with lipstick. I really should watch these with my glasses on. Good explanations, though.

Speak hindi

Too

Your English is not clear

You must be deaf 🙁

Matematiği boşver , sen gel türkiyeye sana kahve yapayım. Bun sorunlarımızı birlikte çözeriz.

Nancy Pi Senden matematik öğretmeni olmaz. Kimse seni dinlemez. Sadece seyreder. Benimde matemetik öğretmenim vardı tıpkı senin gibi, sınıfta kaldım.

Hot logarithmic operations must be the title🙈🙈🙈

1 question. how do u light this setup ? can u show us how do u this behind the scene ? i wonder there is no reflection at all

U r unique bcoz your writing skill

Hi Nancy. I need help with math, especially fractions and decimals.

This video gives a great, yet simple and easy to follow explanation on how to solve logs. Thank you.

0:11 were you writing “in the mirror” with that cute left hand?

i’m pretty sure she is really behind a glass and writing on it “in the mirror” with her left hand. Respect!

I tried couple of times to learn something from her but my intention is not moving from her 😔

So did she write everything on that board backwards?

*_…llogs, lllogs… just wait ’til (neg)Entropy where everything-information is ‘p log p’…_*

*_…I think the ‘strangest’ effect of log, is, that, derivative d/dx xⁿ = nxⁿ⁻¹ except n=0 where x is not-really in the equation, and, because, d/dx ln x = x⁻¹… but then think-about what that means really-close-to-zero n → 0, it looks almost-right but how does xᵋ/ε → ln x…_*

Dicen que todos los zurdos escribimos bien culero :v ella es zurda y escribe súper bien jajaja….

OMG, porque eu não consigo aprender inglês, ajudaria tanto minha vida

pode aprendrer no YouTube 🙂

So, a few minutes ago I was at a some statistics webpage which had a video with an INCREDIBLY low audio volume, so cranked it up to max. Left the computer a while, then got back on youtube. Hey, logarithms (and cute girl)! I should brush up. “HI GUYS I AM NANCY, AND I’M GOING TO SHOW” (panicky lowering audio volume) “… logarithms”.. Oh, shouldn’t have lowered it just that quick (“I swear it was a math video!” lol). Nice video though!

great explanation. Many thanks NancyPi. great teacher and yes pretty teacher…you do fantastic job…keep on posting.

Nice knowledge madam

Nancy, How you solve this: I want to determine how many years a stock will double if it makes 8.56% a year. (1+.0856)^x = 2. Solve for x.

Nice and concise presentation. Thanks.

Thank you for the great video! Keep up with the good work👊

Would yall quit it with the creepy comments for five minutes?

In all seriousness this video was super helpful and I thank you for that.

She is pretty though, right?

For REAL! The cmments are over the top.

We can’t…

That way to pronounce “X” 🥰

I always knew logs where bullshit verbose syntax made up by math nerds to confuse everyone else.

I love you so much.. you just saved my math career😇

You’re the reason I succeed in mathematics

It wasn’t all that long ago that women were not really allowed to be smart, and especially not smart AND pretty. At least we’ve made SOME progress…

was she talking ?

This was very helpful. Thank you so much!

Is she indian

Or an nri

Is she writting everything inverted how could be it possible

Merci NancyPi pour cette vidéo sur le log dont j’avais oublié les bases. Curieusement, le temps passé à vous écouter est plus léger : cela vient-il de votre joli sourire ? Finalement avec vous les maths sont plus faciles : comment est-ce possible ? 🙂

so much in a nutshell

more videos on log

Y’all I think I’m gay ive been looking at her the whole time 💀

I can’t stop thinking of Nancy’s Pi.

Me neither

Unbelieveable

this was pretty helpful.

I usually really like the tricks and shortcuts you show here, but I’m not a huge fan of this way to rewrite logs as exponentials. It’s too “cargo cult mathy” IMHO. I think it’s just as easy, and more informative, to explain the math that’s happening here. You are taking both sides of an equation and treating them as an exponent, and raising some value to that exponent. Then the exponent and log operators cancel out because they’re inverses: 10 ^ (log_10(x)) = x.

So if you have log_3(9) = x, you raise 3 to the power of each side of the equation –> 3 ^ (log_3(9)) = 3^x, then because 3^(log_3(whatever)) cancels, this becomes 9 = 3^x.

Nancy you are a Libertarian teacher! Greetings!

Logs………..oh god.

Unbelievable

Thank you so much. It really helped me a lot!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

I literally couldn’t understand anything my math teacher was saying, and I watch your video and I understand everything perfectly.

What I learned from this video:

She’s damn pretty.

She’s knows math.

She can write backwards flawlessly (Or she just flipped the video).

If only I could get over her prettiness, I could learn that math too.

Flipped the video, exactly

NancyPi se eu entendi bem, você ao escrever, faz da direita para a esquerda.

É isso?

Escreve em um vidro em sua frente e da direita para a esquerda, para que no vídeo a escreita fique em nosso sentido correto?

Letra perfeita.

utilizei o google tradutor

ela vira o video na montagem

@QuitBullshitScience Eu cheguei a pensar nisso mas não me parece efeitos de edição.

Veja em 3 min 28 s uma dificuldade em concluir o traço do “x = 2”

Eu creio que ela consegue escrever as letras no sentido oposto.

Não estou certo disso – sem pensar na capacidade mental para conseguir isso e falar ao mesmo tempo.

Mas se for isso, fica claro que ela tem uma capacidade fenomenal com a matemática.

@Roberto Taveira posso dizer q ela vira o video com o instagram dela, pode ver disso facilmente com o cabelo dela. Oq vc acha disso ?

@QuitBullshitScience De fato eu não sei como elas fez o vídeo, disso eu tenho certeza.

Ela responde isso neste vídeo:

Talvez ela utilize o VEGAS Pro ou o Adobe After Effects.

In fact I do not know how they made the video, I’m sure of that.

She replies in this video:

It may use the VEGAS Pro ou o Adobe After Effects.

NancyPi sim isso é mágico!

NancyPi yes this is magic

Very good!

NancyPi If I understood correctly, you, when writing, do it from right to left.

It is?

Write in a glass in front of you and from right to left, so that in the video the writing is in our right direction?

Perfect letter.

I used google translator (and in the first post I posted in my language. Rssss)

wanna say hi hehe

Its really to hard to concentrate on Maths when she is so pretty…

😱 but.. are you writing from Right to Left..?

OH MY GOD…

You are Great…

❤️❤️❤️❤️❤️❤️❤️❤️❤️❤️❤️❤️❤️❤️

She’s writing normally. The video is mirrored.

Thanks so much

Pretty AND smart…like my math major wife.

Very nice presentation – but – when do you ever come across logs that are not to the base 10 or “e”?

che poppe

I got 100% on this test

Subscribed… Easy way to remind myself things from the high school. Sometimes you go stuff through really simply and slowly, but maybe its sometimes good to just remember the basics. thanks.

🤤 Love Logarithms!

I love you

I’m proud of your lesson!

Nancy is a real one

How many x do you have considering 2019 is not a prime number?

I clicked on this video just to see the comments ^^

Yeah me too

Me too

I need to put a ring on you. Who are you?

best eyebrows ever! (Oh, and being intelligent just makes the whole package that much better).

in 13:22 e^x=1 you said that x=1. but if e=1 then the answer is different and there was no such value given for e. so how did you took e=0. Please clear my doubt???

Value of e =2.71 always. And value of log1 with any base has a ans 0. Because anything to power 0 is 1.

I am sure most of us here don’t even take mathematics yet we are able to sit through a 19 min vid! What sorcery is this?

Mathshasjdabkfkajröa

ı am now engineeer thank you teecher

first time i attend math class since 2014

( ͡°( ͡° ͜ʖ( ͡° ͜ʖ ͡°)ʖ ͡°) ͡°)

best way to teach perverts math

I love you miss you are so beautiful I love you

beauti with brain she is perfect

you got me to the closest of understanding…the basic…..thanks

i thought megan fox is teaching maths

You’re truly saving my grades

Eres muy linda Nancy, saludos desde Venezuela…

thanks mam .. intelligent ,empathic and beautiful

prashant kumar parmanu ma’am*

para hablar otro idioma al mio te entiendo muy bien , mi ingles es básico

Thanks to help others

10:35 fucking mathematicians made our lives miserable by discovering Math but got away with “Undefined” log..

What was the video about, again??

about how smart and beautiful she is.

Tbh I’m not even here for the maths. Here for her beauty😍

She’s so pretty, HOW DOES SHE WRITE BACKWARDS YOURE A WIZARD NANCY!

Kenyce she flips the video. So she’s writing with her right hand on her side of the glass and flips the video

it is so wierd how much i love these…

I grew up in the 90s. I teach math. I tell my students how I remember the change of base formula. When I see a problem that needs the formula I always remember “Ace of Base” for change of base formula. I “saw the sign”… I know it’s corny but it works.

you are a great teacher. Most other go way to fast and are just confusing teachers. I appreciate your style. I learn a lot from you, aint’ you the woman on udemy as well. great all around.

Thank you!!!!!!!! Xxxxxxoooxoxo

So pretty. Also helpful maths video awesome

Nancy I didn’t understand what is e?

Please make another video for it!

Congratulations on your accurate explanations!

Actually I’ve been impressed by this phenomenon of writing on the glass I guess.

Could you explane what and how come? You did it!

Is this mystery related to math!

Thanks in advance for your reply!

Keep doing!

hot teacher

Thank u

Good work Nancy

I like maths, and I like your videos too. Just don’t stop making videos and that’s a student’s request 🙏🙏🙏

Pervert

nice speaker

Nice mam

Great video helped alot

In certain point I noticed that I stopped following the math, and I am just watching with a smile! Beauty with math and I can guess that you are kind as well. Adding kindness will make you perfect.

I’ll get back later hoping to find a similar question to that I was looking for, in your videos.

How can you write like that???

I always memories the rules for powers and logs by imaging that powers are like a ladder to heaven, and logs like the gates of hell. So, “e^(x+y)=e^x × e^y” translated to “When humans multiply, angels have only to add”, and “ln(x×y)=lnx + lny” becomes “When humans add, devils must multiply”.

Logarithms from where???

I have a degree in aerospace engineering but no issues watching this fully concentrated to the end

Yeah math . basically i didn’t understand a word but thanks ,feast my eyes

Is this the same as the captain’s logs on the starship enterprise ? 😎😍🤩😊

How can you write so well in backwards?? what a talent

how t f is this person writing backwards so effortlessly wtf

Jesus… yes.

She should really be doing cloths try on hauls stuff like every pretty girl is doing.

Nancy, thanks for these videos. Content is just superb!

you are Wonderfull and beautifull teatcher. I want you to be my wife, do you marry me ?

I am living in Paris

You mentioned that any number to the 0 power is 1. Does that go for 0 to the 0 power? My calculator says it is undefined.

it’s unsolved. No one knows. even when graphing x^x around 0 we can’t find it. You can even try a bunch of values (1^1, 0.9^0.9, 0.5^0.5, etc, and it’s not monotonous)

Thats because when you reach x^0 youre dividing that number by itself. 0 divided by 0 is undefined.

Are you writing backwards?

How would I contact with u ?

I can watch this all day😊😊

Que Demonios hago acá?, Buen video. XD

Dos tetas pueden mas que dos carretas …

What do you marriage with me

Que bonita

clicked on this instead of clicking on the ones with million views , u know why :V

God the way she explains is just amazing, not to mention how pretty she is. I would have been topper in my class had this video been available in 2009

Thankuhh n u r sou adorable

If she gonna my maths teacher I definitely be 🙃🙃🙃🙃😇😇😇

Nancy3.14

all Math teachers they go straight ahead on solving the exercise, while we need first to know how and where to use this in our practical life, for instance I know that 1+1=2 or an apple + an apple = 2 apples, but I dont know where on the wold I can use logarithms?

so please you need to make an introduction about the practical use of the lesson, which makes us excited to learn it.

Big Greet To You From Iraq

For most people, probably never. However, the main reason logarithm is taught in basic math courses is because it is a fundamental concept. Logarithms are everywhere, though. The pH level in chemistry, interest rates in economics, decibels in sound amplitude, Richter scale in earthquakes, exposure rate in photography, estimating population, cryptography, speech recognition, etc. are all based on logarithm.

@Kyolin wow ! know i feel the importance of learning logarithm, thanks for the info

How to find 5*log(1+i)

@NancyPi 1:20 1:30 you know youre smart and you dont have a problem doing it by thinking of log as to what power. Also, I really enjoy your video they are helping me a lot!

if you guys dont have 20 minutes to spare to figure out the true essence of what she is trying to tell you (even though its a wonderful video)

basically

know that log3(9) = 3^x = 9 and youre solving for x

writing out your logs in that format will simplify a lot of your log solving concerns

ln 3 means e^x = 3 (e ≈ 2.71828) e is a constant, meaning its a number an irrational one

same thing with ln functions, just write it out

ln e = 3 is easy when you realize e^x = e^3 x has to equal to 3

Have a great day!

All of her videos is just basic math that we’ve learned in high school or first year college. I allready understand with this topic. But it’s okay because she is pretty.

I did not have to watch it. I watched.

wish she could do Algorithms instead of simple logarithims if only beauty was proportional to the level of intellect she’d be rather doing algorithms

I think her beauty is indeed proportional to her intellect as I’m sure she can see that algorithm and logarithm are two unrelated things.

@Kyolin You miss the point completely, you seem to be a sensitive person who tends to be defensive without actually comprehending the details and moreover lacks deeper and logical reasoning. I feel sorry for you but i agree to disagree with you

if someone has a teacher like you, do you really think students are gonna concentrate on topic?🙈😂

Yes they can Hawas k pujari

I don’t understand, do write backward?

This is so helpful, also your voice is very beautiful, which I never knew could help me understand math haha.

What is name of board

Because I’m not know this board

its called glass

You are looking beautiful and talented…

Why we use logarithm problem and where use it….

I love u

Hello Nancy you r pretty but incomplete without someone…

U guess who’s that

Wow… bastard

I definitely needed this video. Very good refresher for me. Thank you.

How are you writing backwards? My mind is blown. Is there some trick I’m missing..?

The video is flipped obviously.

how on earth are you writing backwards? wow but seriously thank you for this video and speaking slow and clearly

video mirror

My whole school life is a lie when i was told the maths teachers are supposed to be ugly nerdy and without the sense of dressing and i decided to skip that subject as soon as I was given an option to choose my course after high school.

you could make a fella believe 2+2= 5

How writes on screen?

Drop dead gorgeous and a great math teacher, I have found Nirvana!!

Hai

i wish u were my high school maths teacher, i wasted my brain by memorizing stuff

We aren’t allowed to use calculators from where I’m at.

Thanks a lot Nancy

I just realized she’s left-handed

are you able to write down the equation which satisfied heron’s fountain and endless supply of energy and electricity bills are going to decreased for forever for mankind’s😕😕😕😕😕

google – What is 3 to the power of 9 and the answer is: 19683

it should be what power to put on 3 to get 9!

Better to do it long hand…to see the steps of the breakdown.

Dude I bet noone subs for the Math lmfao this chick is so hot and watching her do math makes her so much hotter its unreal

I can’t understand why would someone use natural logs, not knowing what Euler’s number even mean… (I’m talking about 12:26)

She is really a gineus, she can write in opposite to custom. Beauty with brains!

I noticed it when a person mentioned it in his comment.

Mirrors are simple to use.

Software image flipping is also easy to use.

Dear Nancy you have taught log very very comfortably and I have understood the log now and also you are beautiful.

No Ring in finger.

There is hope. YESSSS

You meant to say “No ring ON finger”,..not IN finger.

If women wore the ring IN their finger, that would be quite painful, and no one would ever be able to see it.

Of course, with your line of thinking, maybe she does have a ring IN her finger? :oP

@panda44r I’m surprised you understood what he meant; it’s as if the internet doesn’t need exact spelling, all the time.

@Zork The Destroyer – Um, go zork yourself

How is she writing backwards?

Name two left-handed people who can write backwards . . . Leonardo da Vinci and NancyPi

Beauty + talent wow👌

Wow I’m suddenly much more interested in maths for some reason

yes

i accidentally forgot what she was writing because i was too busy staring at her oops

Did she just do mirror writing with left hand? ♥♥♥

She is using her right hand. exactly!

at my school we’re thought that the when we write lg instead of log it’s implying that the base is 10.

Yeah right. I think that she wanted to write lg but instead wrote log

swaad aagya yr

If analog computing is still being done. The feed back capacitor on a FET can be used to generate a log curve. It gets to be real fun. That is if you are solving for X, when X is part of fractional power. It is relatively simple solution that can be done with a few hundred thousand lines of code or nine electronic parts. A task that could use this. Calculating the air fuel mixture with the output from a a oxygen sensor. That could be fed to another to calculate the pulse and timing for a fuel injector. The problem is, it is easily understood and your .gov does not like easily understood and neither does the car manufacturer.

Admirabile Mirifici Logarithmorum

Nice one ma’am

#rqphysics

so hot… never thought math can be so sexy

I’m here just becouse of her 😀

How do you write backwards?

Hey Nancy love you

😍

You’re hot teacher☺️☺️☺️!!!!

Hott

if all be solved through calculator why u are here..

OMG

Beautiful, smart and can write backwards math demonstrations

i watched the full video and I don’t even have an interest in science

This is the best lesson I’ve ever had in my life. Thank you very much

around @2:40

it’s easier to write out:

log3 9

with plenty of space between the log3 and 9, then just pop in an eXponent (on the same level as the 9) and equals sign between the log3 and 9, then cross out the log. yielding:

—3^x = 9

because the 3 is a subscript in the first place, writing a normal x next to it, then crossing out the log makes it look like a normal exponent. and this way you only write the thing once, leaving less drama all over the page to get confused by.

@9:21

you should have started the whole topic of logarithms off by explaining how powers work:

3^4 = 1 *3 *3 *3 *3 ; start with one and multiply it by the base exponent times

3^0 = 1 ; start with one and do nothing, because the exponent is zero, so multiplying one by the base zero times yields one

3^-4 = 1 /3 /3 /3 /3 ; start with one and repeatedly divide by the base because division is the opposite/negative of multiplication

afaict, absolutely nobody teaches powers this way, but it is correct and makes everything clear in just 3 lines of notes. and now you don’t have to randomly memorize that a power of zero yields one, or a negative exponent yields fractions, because all of the parts have a meaning and those meanings all contribute and make perfect sense.

you might notice that this has a few broader implications, too. for one it means that the correct way to count is to start at zero, and in practice this pans out, because before you can start listing off numbers you must arrange the stuff you’re counting with a starting place, the edge of that starting place which you will use as reference to count from is zero. additionally, zero is where coordinate systems propagate from, and where operations like division (iterative subtraction) and integration terminate.

this also implies that every number to the zero power is one, because it is now the definition of how exponents work. this means that mathematicians who view 0^0 as undefinable are wrong. and when you look at why they believe it to be undefinable the reasoning is faulty anyway, even if they were correct, because they’re looking at a discontinuity around 0^0 as evidence that it can’t exist. but it’s trivial to make such discontinuities that can be evaluated, so that’s not actually evidence of anything. it’s essentially like arguing that you can’t get inside your home because you can’t get into it from every single direction, which is clearly absurd.

this account of powers also aligns with a thorough treatment of n-dimensional volumes. here all you can say about 0-space objects (points) is whether they exist (1) or not (0). in 1-space you can measure length (1 *x). in 2-space you can measure area (1 *x *y), but since all shapes can be bounded by a rectangle they’ll each have their own shape constant (which are values between 1 and 0, since some of the points in the bounding rectangle exist, while others do not), like 1/2 for triangles (1/2 *x *y), or pi/4 for ellipses (pi/4 *x *y). in 3-space you can measure volume (1 *x *y *z), and again all shapes can be bounded by rectangular prisms, and so have their own shape constant, like 1/3 for pyramids (1/3 *x *y *z), or combinatorial shape constants, like for a cone (1/3 * pi/4 *x *y *z), or a sphere (2/3 * pi/4 *x *y *z).

you’ll probably notice that I’m using pi/4 rather than pi as the fundamental circle constant. this is also for deep reasons, only one of which is that it exists between 1 and 0, which is required for shape constants. for one, it’s the angle around which the trigonometric functions reflect, so that the prefix ‘co-‘ effectively means ‘reflected across pi/4’, so that cosine = sine reflected across pi/4, cotangent = tangent reflected across pi/4, cosecant = secant reflected across pi/4. it also relates both area and perimeter length to a straight line length on circles, which is insane. further, the traditional equation for finding the area of a circle, a = pi * r^2, follows a paradoxical philosophy because if you applied the same method of finding area to a square (the fundamental unit of area) then it would be impossible to find the area of that square as you would fall into an infinite regress, as taking the area of a square would require finding the area of a square 1/4 the size, which then requires finding the area of a square 1/4 of its size, ad infinitvm. using a = pi/4 * d^2 avoids this paradox, being a method that extends unproblematically to all shapes. additionally, all of the other proposed fundamental circle constants, pi/2, pi and tau (2 * pi), are power of 2 harmonics of pi/4, or more importantly, they’re the multiples of pi/4 which align with axes of symmetry on a square, pi/4 representing a 1/8 right triangle, pi/2 representing a 1/4 subsquare, pi representing a 1/2 rectangle, and tau representing the entire square. these are precisely the lines of symmetry on which the ellipse/circle constant pi/4 relates both area and perimeter length, and thus all of the previously proposed fundamental circle constants are simultaneously correct and incorrect, because they inherent most, but not all, of the properties of pi/4.

Sorry this is not how you learn Logarithms!

Nice and easy when you use easy numbers and know the answer reverse teaching bad.

Weird is not a math or scientific term

“Undefined” why not draw a log graph then you can show that you cannot have -1 or 0

What’s e? its a “special number ” WTF (compound interest /exponential growth and decay)

This is seriously not even early high school algebra

log10(7)/Log10(2)=0.84509804/0.301029996=2.807354922 (Weird numbers)

This is just titty click bait! I did give it a thumbs up but!

the snail method, It’s a ‘logarithmic spiral’ lol

Just wanna say: I have an undergrad degree in math and learned some stuff. This was exceedingly well-paced and well-explained. Great work

Navy I really like you

Nancy

So glad I found your material! I have a test today and was having a bit of trouble. The way you rewrite it out first makes it so much more simple to understand. My professor didn’t explain it quite as well. Thank you for taking the time to make these for all of us who struggle! Also, you write backwards perfectly!

What an awesome use of dyslexia.Writing backwards for our benefit!

Great tutorial and explanation!

Thhhaaannnnkkkk yoooouuuuu sssoooooooo mmmmuuuuucccchhhh 😆💖💖💖!

e^(pi*i)=-1 … so couldn’t log (-1) have a solution???

I know all of this… but still watching…

she looked so innocent so far and then…. 19:09 hahahahahahah!!!

i love math now

I’m 61 years old and never got Logarithms. You make it so easy and concise. I do have one question: what is a practical application or purpose for logs. That’s one of the reasons I did not understand a lot of upper level math. No real world applications given during the instruction. Thanks again.

She is more than a math teacher ‼️‼️❤️❤️❤️❤️❤️❤️❤️❤️❤️Can we get married ?????? ❤️❤️🙏🙏🙏🙏🙏🙏🙏🙏🙏🌹🌹🌹🌹🌹🌹🌹🌹🌹🌹👍

Nancy mam is beautiful

I LOVE U…DO U LIKE BLACK MALES ?

I’m OK with black people. Is he Shaq in your profile photo?

@Soda Rehberi no one cares about u . i asked Nancypi whether she likes black males or not . i like to take her on a date .

capitalistic way of approach….get the answer any which way…coz, I need to loot students for more and more money…heck, teach what is log and why exponential and logs are convertible…then go for examples….Free tip for interested students: Read the Soviet math book “Areas and Logarithms” by Markushevich” to understand the why and what of logarithms and areas…and then continue solving examples…no offense plzzz….

Thank You!! I’m also on summer vacation heading into Pre-Calculus . The mnemonic device (snail) works for me!!! And I’m 67 yrs young. Great teaching method!!

I wish I had a sister like you <3

A SISTER !?!

Your are Beautiful <3

Hiii call meeee

ily Nancy

I pray to God this woman comes and visits me in my sleep. Beautiful facial muscles :3

is there an imaginary solution at 11:00 to the question on the right?

Yes, imaginary numbers let us solve ln(-1) = πi and we can also use limits to say “log(0) = – infinity” … It baffles me why lower level math classes teach absolute rules that higher level math classes show are not absolute rules at all.

@Ronald Jensen Hey, thanks for the reply. I’ll look into those.

You are nice! 🙂

Ah! This is frustrating. You do a fantastic job; im just slow. I one of those that needs an explanation for every little step.

You are an amazing teacher.

thank you very much

nice§

Why does she assume that log 10000 is to base 10?

Thanks

That is a common convention in elementary math… In computer science it usually does not hold true, most programming languages use “log” as the natural log by default.

i am just totally into you

Fuckin’ BS comments

Hey beautiful teacher, is the answer for the last question 2.807??

complex numbers: log(-1) = i*pi

If the basis was e.

I can not. its too difficult for me ………. I can not even keep on listening to ur voice ……im getting crazy as fuck

No, thank you for your help with this one.

e to the x, dx, dx

e to the y, dy, dy

ASMR + Math + English Class. This is why I like Youtube.

I have a comment. Instead of teaching us mechanically plugging values, why did not you start with why even logarithm came into existence? such background can help the student to stick longer with the concepts.

я не пойму, у неё с дикцией проблемы, или это манера речи такая?

It’s just any native person’s way of speaking. Clear, understandable. But if you’re a beginner in English, it wouldn’t be that understandable.

кстати, я учу русский ❤❤🙂

@Soda Rehberi pay attention to her teeth and mouth during she says words which have letter “L”

💖 hot math

yes how does she write backwards

She goes in to Video Editing and just flips to Mirror Image and so it switches Left Right to Right Left so it reads good for us… Geometry!

Which techniques do you use to write plese tell me

Hi Nancy, Hi Everyone. You didn’t tell us that we can pull an Exponent out of the Argument of a LOG or LN and set it out in front, so that LN2^3 is 3LN2. It often makes things a lot easier knowing that one can move that Exponent out.

Now my life has meaning?

Napayım yani NAPAYIM Türk öğretmenler güzel anlatsin djdj

how a nice lecture she is NancyPi surely you should be a teacher from God

Nancy how u write backward ??? , please make a video on this

Just flipped the video

I was opening the YouTube app to listen to some lullaby to make me sleep, but found myself not blinking for the last 20 minutes and learning the basic of Logs. Her teaching method is so easy and calm that it’s easier than drinking water. I feel like I’m hypnotized. Lol

Well taught! Thanks for the lesson!

Can you teach me your personal logarithms to be your boyfriend?

Please describe about Fourier series

I just stumbled onto you the next time I watch it I’m going to be sober I love this stuff I wish I could understand all of it I’ll be seeing you again sober

Math is secandary things but how you are teaching in white background 😍 ye sikhna hai mujhe

nasıl ters yazıyor lan

Very good!

This young lady is remarkable: lot’s of video’s on calculus, trigonometry, algebra etc and they are all easy to follow with simple to follow notation. Really fantastic stuff!

It took me about 3 minutes to figure out that you are, in fact, right-handed.

Really!!!

how?

@shinobi She writes on a screen in front of her and then the video is flipped left-right

@Ornicar Ornicar your explanation right 🙂👍🏻

some NASA stuff…but nice 🙂

Very interesting

The teacher writes backwards

I’ll save and watch later

The first time I watch a lesson on Logs and I actually like it.

👍Awesome👍

log3 of 9 -> ln 9/ln3 -> 2.

how come she’s so bright ? this ain’t fare !

Physicists: log to the base of an electron….hmmm…hmmm…

Another one:

take x, raise it, care for it and provide for it, send it to college, pay its tuition fees, and when it becomes 32, you never hear from it again!

cool jokes mate, thanks

Superb mam

I don’t want to be disrespectful. But, better than an intelligent teacher, is an intelligent and pretty teacher.

Trust me if you was my teacher when I was student I would never miss even a single class. You are really beautiful!!!

She is so pretty and sweet! It make fun to lean from her 🙂

she is comfortable writing reverse on screen

I can’t listen to this because she is so cute!

I really liked the way you explain this, Liked your Videos

NensyPi you look very nice, would you be my girl? 😉

She’s right handed and reversed the video.

O O

O Mind blown

none of the boys were ever late for that math class

She is a robot overlord. An AI if you will. Oh man, they know just they are doing.

how do you get to write backwards?…

she has beautiful shoulders and arms.

I am in loooove in………her’s………….logarithms of course.

I love the method of presentation.

Write on a window, and flip the video.

Beautiful. That way you’re looking at the camera and still writing. Beautiful.

You just solved the mistery.

Thank you.

Finally math is interesting

I LOVE U

WOW

Thanks you Nancy !

How do you get log to base sin(X) of cos(X) = π. We never work with numbers.

idk what level youre at, Im in my last year of high school here in the UK tho, sorry if I use something you havent done in school but this is what I could think of quickly. Take that log and change it to sin(x)^pi = cos(x), then rearrange equal to 0. Take the derivative of that function then use the Newton-Raphson Method with x0=0.5 to converge on the root, which gives x as 0.979538. Probably an easier way to do it but this works too

Matter always split in approximately 2% finer graining. Other things are energy form.

Venkatesh Babu Ponnuchamy what are you on about mate

Megan fox the math teacher

18:12 =7 ; rules to the seven must apply then to all prime numbers.

i was in love with my religion teacher. she was so sexy and hot oh god

Why log base 10 and not log base 100 for the second example

Because we use a base 10 counting system

Oh default is 10

Needless

Say divide the argument number with the base number untill the reminder is 1 ( base number / base number )

Back in the 1970’s logs were a little book that you used to do complex arithmetic. This is a lot like a mix of algebra and quadratic equations.

The energy is good but your path between what is in your head and mine is completely tortuous and leads not to any value. Please imagine explaining to a kid and from there base your lecture accordingly! Good luck

No se si con una profe asi vas a prestar mas atención o te vas a quedar mirándola toda la clase XD XD. Porque no tuve una asi cuando estudiaba???

My GOD so hot maths teacher….She is quite sexy….I am really flattered….

Thank you! You have such a calm and clear way about you.

I didn’t know there were so many dumb people. Jeez. Like wtf is wrong with you.

do you guys start studying this at college?

we learn Logarithms here first year of high school however the program has changed now and they dropped the level drastically and they start studying logarithms second year of high school because students were complaining it’s hard while true reason was people never attend the classes in first place, but i feel cheated tbh although i managed to do them, i never truly understood them this simple like you explained, a reflection of the bad teacher i had and always in conflict with, flavoured by my laziness.

am relearning everything about Math, thinking about maybe getting new Bachelor degree, hope your channel has what am looking for

Is this really the way now how people learn basic math? What happened to elementary schools?

This is Voodoo and WitchCraft is all that it is they try to Make it Look Like It’s the Norm and Healthy for Your Mind, Body and Soul It’s Not, Don’t you Remember the Apple Sitting on the Teacher’s Desk? Damnation .

In love with you♥

Mirror image….. hacking of handwriting…..,..

Kind of trick to attract more subscriber bro

I don’t think so…..she has good teaching skill and she is pretty too

I have no idea what she’s talking about, but still watched for some reason 🤔

😋

Same

Hello 3.14159265359 how are you???

marry me

con una profesora asi no pierdo una clase

If you are my math teacher in the school, i will never absent in math class.

“Looking at this equation, you can just tell.” As a programmer, this cannot be enough. Why not show the next steps in solving the equation instead of asking the user to brute force it? At some points in the video I could feel my high school algebra screaming “x is solvable!”

This looks easy but i remember from school we had equations that took like 5 A4 pages to solve and that was the point where i gave up

kkkk ,omg ,

@Percy Charumbidza hey don’t cry

Nancy you are holding pen incorrectly with 3 fingers. This may be due to your right shoulder bent to much inside. This may be corrected with some exercises.

Linda

Great tutorial!

Man I love ur brains where did u learn that method ,u solved my very old confusion on solving logaritm,u got a beautiful brain ,

Hello woman, I found the video very nice, but then I thought that women can not be intelligent and you wrote there is not right. Please, please also the right one write white, vllt. you do it differently but that’s not math. Just as I learned it from a doctor in math, you write somewhere but not mathematic formulas.

it’s really difficult to look at what she writes. I can’t take my eyes off her.

im trying to figure out why this got recommended to me i search pies smh

Thank Mean

Apki voice achi hi

nancy you are so cool

‘Log a to the base e’ is something I’ve not yet understood. Can you explain them in detail.

With your help, I studied and tested completely out of pre-calculus! Thank you much.

Hiii how r u ,iam from india

yeah yea whatever, what did you say your name was? haha. it would be literally impossible to concentrate with a teacher that hot in front, thank god most math teachers are not that pretty, I still don’t know how i ended up here

Very nicely done enjoyed it,

Super nice lady u look at her and u want to learn wish I had her for a teacher when I was in school and

I’m 76yrs old

Does she write backwards?

I believe they just mirrored (flipped) the video.

When did math become so fine?

She reminds me of my high school algebra 1 teacher, I almost failed. For some reason, I just couldn’t concentrate on math.

Who is here just by watching the thumbnail (mam).😋😋😍😁

Pretty awesome backwards writing. Respect!

Thank you ma’am .

3:40

Great Explanation!!!

Helpful 🙌🏽

If you were my teacher, I will become a genius now

Wow rare case, a pretty girl teaching maths 😋😋😋😋

Mine First foreign teacher

Iove from India 🇮🇳🇮🇳🇮🇳🇮🇳

NancyPi is Very Hot!

excellent video thanks!

The way she appears to “write backwards” could be as simple as her writing normally, forward for herself on the back side of glass, and initially appearing backwards to the camera, and her flipping the video horizontally.

This has nothing to do with flipping a camera/ video sideways. Rotating a camera sideways will only film the event sideways. It won’t reverse numbers and letters.

We know there is a clear media between the viewer (us) and her. That means she is facing the viewer as she writes. We can attack this from either the viewers’ perspective, or from her perspective. I’ll use the the viewers’ perspective.

1) Let’s say she uses a “normal” video camera or a front-facing camera on a smart phone and she is right-handed. If so, her hand would move away from her, as she wirtes (it does), but the words are written reversed AND written right to left, from our perspective.

1a) Now let’s say she’s left-handed. If so, her hand would move toward her body, as she writes (it doesn’t), and the words are still reversed AND written right to left, from our perspective.

2) Let’s say she’s using a smart phone and the camera feature is reversed, meaning as you look at the screen, you see yourself, instead of what is in front of you. This feature produces a mirror image; your right, is the mirror left. Your left, is the mirror right. Let’s say she’s left-handed. If so, from our perspective, it would appear that she’s right-handed, her hand would move toward her body (it doesn’t), the words would appear to be written backward AND written right to left.

2a) Now let’s say she’s right-handed. If so, from our perspective, it would appear that she’s left-handed, her hand would move away from her body (it does), the words would appear to be written backward AND right to left.

None of these scenarios work. But they all have one thing in common, the writing will always appear to be written reversed and from right to left. So, we can deduce that she is definitely writing backwards. Left, or right-handed, will depend on the camera set up. “Someone” said she’s writing backwards, she is.

@Ron Nancy Pi’s If one visits the bridge of museum military ships, for example the USS Intrepid, anchored at Manhattan, NYC. There is the clear polycarbonate scree where a sailor writes backwards behind it for the officers to see on the “front” side.

@Ron underated

big brain

She’s explaining complex mathematical concepts while writing backwards, and I can barely do long division and write forwards.

Wow… Nancy

you make math bearable hahahaha, thank you for taking the time to teach us dummies!

I think now i got the idea on how she write that thing😁

thanks

Is she really writing backwards or is this special effects??!!! Either way, great job!

Hello you’re so beautiful 😍😍😍😍😍😍😍😍😍

I AM INLOVE ON U NANCY!

thank youuu your videos are well paced and easy to understand keep up the good work!

Thanks!!! :::::)))))

Im just dumb even do she explains it soooo well

Really?

At 7:30 why cant 1/8 be written as 0.125?

It can but it won’t help you to solve it. Writing 2^3 makes it easier!

Like Ben Eater, what we have in NancyPi is a gifted teacher. OK we don’t know how either would go in a crowded classroom, but when it comes to the method of teaching, Nancy and Ben (and a few others) should really be giving lessons to teachers, not us.

Calm, methodical, no skipped steps ever, no assumptions, no “Flashes of Genius”, no talking down, personable. Eddie Woo is good too, but prone to wizardry and showmanship. You could get left behind in his class because he teaches to the bright ones.

This is really helping me to revisit the fun I had in math. I did not use the math but I had fun. Its too late for me now but I think I might take a math course.

beauty with brain

Thanks Nancy, the snail works

What a hot girl

Thanks Nancy.

Vvery bad because we saw oposit side please change your write

You have helped me bring my grade up 15 points so far. Thank you

Can anyone tell me what editing software lets you make that gradual speeding up and slowing down effect? And that tape winding noise that goes with it?

Mathematic! You are awesome. I hated logs in grade school, college and grad school

Hi my mentor

Thank you

I have to re-learn all sorts of complex math for a software engineer coding test. I’m mostly a front-end design person. RIIIIIPPPPP

Percentage of straight girls learning from this video: 83

Percentage of all men and lesbian woman learning from this video: 2

(To clarify, even gay men get distracted because they become jealous of her complexion…)

Everyone commenting about how she writes, her beauty, or just math, but here I am thinking how clean and clear that glass she’s writing on

i may have scored full marks in maths if she was my maths teacher 😭😭😭

Wrong

so what is the function or use of logs in math? I do not see the purpose

You’re voice is very clear and not too high.

You’re a perfect teacher!

But she speaks a little too fast at times.

Thanks 😊 great video 👍.

Each word in its place,clarity, well passed and beauty. Thanks.

Lovely Video

I fucking adore her voice.

I really appreciate your videos. How can I contact privately to assist me on some topics in Mathematics. This is my contact or Wharsapp line : +23230328443

Log base e? Don’t be so irrational!

Are you flirting at 14:21?

Nancy is literally the math queen. thank you so much girl <3

Your Teaching method is excellent.

It’s all algebraic with no geometry. It’s ok but it isn’t “perfect”.

@ClearOutSamskaras I did comment on teaching method. I did not understand what are you saying.

@ClearOutSamskaras Teaching method do not relate algebra and geometry

You are patola

She’s not only gorgeous, but very cute as she sad it so humbly in the end “….but you can like my video and please subscribe!”

Keep it up dear…!

Yo im done with school I just clicked cause she’s hawt

Mam first you are very pretty and you are the best teacher foreever

thanks a lot

Thank you very much! I had to get a BA instead the BS in my field because I couldn’t get past a certain portion in stats class. I wish I had you for my professor. But also I learn better when it comes to math in small groups or one on one. I never thought I’d understand logs and in a few minutes I not only learned them but found it interesting.

Thank you Nancy!

I wonder if you are writing in reverse? Very impressive effect anyway.

Hi ms.nancy how about (-i^-i) what is the equivalent in exponential form? Thanks.

NancyPi mam, If I’m not wrong you were writing on rectangle mirror and recording it in mirror image.

Please do not forgot to reply me.

Thank you.

I think she is right handed… writes on glass in front of her and just horizontally flipped the image in the video.

I am more motivated to learn Math because of youu!!!

You’ve got another subscribers! Your so talented sis. Thank you soo much for making this video, God bless!

how TF is she writing backwards like that though?

waste of time

Who is here after watching the thumb nail?

In nepal, all math teachers are male.. They look like fatter, strict….

How pretty she is???

I would surely score A+ in math examinations if she were my teacher.. Love u mam from nepal

Well understanded you explain

Things very well ,I’m try too

Revive my memory. When

I had a tutor. I comprehend what

Your say about certain things.

Thanks 🤓🤩👍😃😃

i want to meet you pls.

So beautiful and at the same time intelligent , i really hope you we’re my prof. in math 😀👍👏

Your beauty is mathematically mysterious.

If I had a teacher like her I would never be able to concentrate in class. she is beautiful.

(ln(x/100))^2 :——–> x=?

I love you too.

Nancy Pi video makes me feel like a math wizard whos gonna get A in cAL1 and go on to beat all 4 bosses including the 4th and final boss at differental eq…haha. .BTW i been outta high school 20 yrs..hard to believe #vetOIF04-05

i wondered how she is writing this way… of course it is flipped video. If you see her Instagram…her face looks very different because here we see a mirror image of her

Nancy, when you drew a snail, that was the best way that I understood how to rewrite it. Cute drawing!

I dont know why all of a sudden I am watching Logarithms video in the middle of the night….while I have office tomorrow and I am an IT consultant and probably never going to study math again in my life 😂

Even weirder thing is you’r a girl.:D

Teach Ur kids.

hahaha!…..

Subscribe to my YouTube channel

I didn’t like mathematics but I love it now coz you r so attractive and gorgeous.

8:21 thats called recipocal form

Welp. I just have no words for #2. I’ve been doing it wrong all this time making my life hard this past week lol

I don’t need this type of tutorial but I watch every your video …. because of your beauty..

Love u ma’am thanks for teaching

i know this is probably outside the videos context, and im new here (but loving it), but the snail idea is pretty fun and cool. its also in a way used to figure out what c declarations mean (c as in the C programming language,.

not sure how deep nancy goes, or if shes even interested in programming. just saying…

love your stuff keep it up!
