• This video reveals your trick 😉
Thanks for the Q&A and thanks for the math tips

• Uuu i like that magic
Hair line on the right instead of left like in previous videos.
Right handed, not left like in teaching videos.

You have nice content on your channel. Thx for the teach 🙂

• Kalash55 👌🏼

• She simply flips the video on the X-axis in the video editing. I am now a wizard.

• This was good. Also your editing was fun. And thanks for the math help.

• You made math enjoyable thanks

• You should change the name of your channel to:’I love Nancy’ because indeed you have a very likeable personality

• I can tell you why can write backward l had a secretary who could have written backward. She was ambidextrous. But any left handed person can write backward

• you’re incredible

• After finishing this video I have one important question, will you explain any math logic courses?
like Discrete Math and those ones for CS students…?

• mathgician

• it’s okay to be nervous fam

• Thank you for providing me with education for all these years

• I love watching your videos. You explain things very well. Could you do some Calculus III videos? Like vector projections & more.

• She uses a lot of her right hand in these videos, and in her math lessons, she uses her left hand. Think about it, and you will know her secret.

• Hmmm, I bet the trick to writing like she does is finding the inverse, then finding the inverse of the inverse. In other words, it’s highly probable that she’s right handed. lol

• Haha… tapping the nails on the phone.

• Ok I guess Nancy does nor write backwards, she is obviously right handed, and is writing normally, then she mirror images the video left to right so it looks as if she is magically writing left handed backwards in real time!

• Nancy ur a beauty

• Actually i know….you write with your right hand…and give the image ‘mirror effect’…or you laterally invert it!!

• thank you so much for helping me not flunk!! I’ve learned a ton. Please keep going. You’re amazing!

• nancy you aren’t as robotic in this video… and your eyes aren’t as dilated

• Q and A top question…..Will you marry me?

• MIT?

• If is not post production, I think it is:…………….

She writes on a glass, the camera records the in a mirror. So she really writes with her right hand… and because if lateral inversion in a mirror we see it as her left hand.

• You are gorgeous, I have never seen your smile before, and I must say it is a most beautiful one

• Anyone else notice the bag that kept jumping in and out of shots in the bottom left?

• Miss you were chemistry

• LOL. I was a “wizard” before you… granted, I was a lower tech and not nearly as photogenic wizard, with a small apartment and limited resources at the time. I have only 16 videos on my channel that I did during my return to UIC for ChemE degree.
Keep up the good work!

• 2:08 I appreciate the fact that you said “maths” and not math

• Great channel.

• i love you i love you i love you i love you i loveyou

• ew

• I am so happy for you getting your own channel. I really would like to see you do more 3rd semester calculus problems (gradients, triple integrals etc) maybe differential equations. You really make this fun and enjoyable in so many ways. All the best!

• Can you do more non-math videos?

I’m not here for the math….

• I am here for maths only!!! no that is not true 😍

• i wish you never commented this

• How are you so beautiful?

• Hay congratulations 100k

• Another idea for a future talk video: career opportunities for math majors! What kinds of interesting work can math majors hope to find after graduation.

• I often used your MATHBFF videos a few years ago in my tutoring in algebra because they are so great. Now I’d to use them again. Are the old ones still available? Please say YES. Thanks, volunteer math tutor in San Diego

• U should start a asmr channel for real tho

• I wanted to know was how she wrote backward so well.
Also, how she so hot and smart?
I love pasta too and don’t know how to end things

• Bob Ross!! Cool. 🙂

• I so appreciate your videos! It was nice seeing a bit of a personal type video. Your voice is very calming and I really appreciate you breaking down the steps…which is totally needed as I take my Calculus course!! Trying to solidify it in my head!!

• What do you work

• Doesn’t hurt to be super hot.

• I need to take lesson . Sure not free ?
Please agree to give me lessons and I am ready to the cost for these lessons

• Ideas:
-Pasta math. I don’t know what it is, but it could be something. Antipasti would be imaginary numbers, obviously.
-Weird and unexpected results from math. Like the Game Show problem, infinites, Mandelbrot set, my high school report cards… etc.
-Recite pi. In it’s entirety. Backwards from the end. (I would watch all of it)
-The statistical probability that the end of the world is near, and that it’s because Kim Kardashian had a baby with Kanye. I’ve done the math, and I keep getting 99.999% to 9 standard deviations.
-Make one video on day one. Two on day two. Four on day three. Eight on day four. Keep doubling each day, until I get bored. On day 64, play chess. It’s called the Chess challenge. I made it up.

• So beautiful and smart..

• Very funny, great presentation. Questions, ideas… since you are a computer science person as well as a math person, I am interested in learning more about and achieving fluency in the areas of math ther pertain to comp sci. Different bases are an example of a starting point. Or factoring because it relates to cryptography, etc. Pure math is great, I only discovered that late in life. I suppose many people are looking for practical solutions, and I think computers are a great place to discover how wonderful (necessary) math is. (I see a similar comment just below this one; I know I am not alone in this notion.)

• You have some really high quality content on your channel. Nicely done!

• What is ur nationalisty ??

• omg you’ve got such a good personality!!

• Here’s a question for you–how would you like to be my next ex-wife?

• here is mine. what type of workout do you do ?

• You are the reason why I started liking calculus lol

• 1:05 How do you write backwards? She simply flips the video after she is done recording;and no she isn’t writing backwards!

• MIT is expensive;how were you able to pay off the tuition fee,do you come from rich background?

• lol… You have no idea what your videos has done for me. Ran from math all my life thinking i wouldnt need it.. Pssh! 🙁
Magic X has changed my LIFE and a few friends that i imparted the knowledge to 😀 HAhaha

• Do you know you helped me finish calculus and loved it . I’ve finished Calculus 1,2,3 easy and it all started with you. Thank you Nancy!

• Thats what i hope for…have Calculus nxt semester

• You are the cutest math teacher in the world. It will be an honor to have you as a friend and off course keeping math apart even though I calculate a lot and teach Math the whole day.

• You write on glass and mirror your videos. That’s it.

• How do you explain using determinants to solve systems of equations?

• She mirror the video to write backwards.

• very cute!!

• stfu

• Alot of cherry picked non questions.

• Could you do a video on consecutive integers, please?

• Does this girl have the total package, beauty and brains?

• For the first question, I think there is a projection of what she is about to write, so she just traces what is projected. Add a bit of cleverness and you’ll have some fooled viewers!

• Thank the lord for this woman, massive help

• I enjoyed this video way more than i would

• Nancy u said you have passion for computer science then make a video for coding.

• Super Cute😋

• you’re probably a fat kid that can’t any girls shut up

• Nancy, math and computer science teacher here 🙂 Can you do a video on Boolean Algebra?

• I think she flips the video so the writing is the correct way round

• correct!!!

• How she writes backwards, well thats easy. Everything that you write on a posterior side of the transparent surface on camera will look in reverse, the only way to correct that is to mirror-flip the image in post production, which by the way creates another interesting effect that proves the above. In this Q&A vid she is holding her mobile phone is her right hand, its safe to say that she is right-handed, but in all her math videos she is holding a marker-pen is her left hand, this effect is caused by the “mirror-flip”.

• Can you teach more subjects like physics,biology or chemistry?

• West coast is the best coast NANCY

• Is there is your another account

• How can u solve f(x)=5÷2x_4

• Thanks for all you do! You’re channel’s been a great resource for me through Pre-Calc and Calc 1. I hope you feel awesome about that.

• a bit of a silly question here, how do you write backwards so well?? are you a wizard?

• she mirrors the video, she writes on a glass.

• YES CAN U EXPLAIN WHY ANY NUMBER TO THE ZEROITH POWER IS 1. Also maybe the traveling salesmen problem if you have time lol

• If you see that
4!= 24

You divide by 4 to get:
3!= 6
You divide by 3 to get:
2! = 2
You divide by 2 to get:
1! = 1
You divide by 1 to get:
0! =1
Just one way.

• this is really interesting.. you hve answered a lot of my questions Nancy. super cul

• *Nancy people are not loyal to you, or to your teaching skills (they are good though), people are here to see your face.*

• Strange but nice. Personally I would like to see a session just devoted to the use of symbols. When I was a kid each year at school was like a barrage of snowballs thrown at you. How helpful it would have been to have been given an overview from the start; a kind of “heads up.”

• fun

• I remembered watching your former channel because you teach better than my profs to learn maths when I was still a freshman 😂

• Did you say that you are into computer science? Will you make some videos on that please?!

• Can you solve the square root of pi to the power of negative infinity, I’ve already solved it, I just wanted to know if you can do it.

• Math Lovers pro level questions zero

• @Noor Nedal correct

• You are a genius – and a beautiful personality! Keep up with the good work on math videos – I always learn a lot!

• My sister was naturally left handed but in the time and place that we grew up in, it was not acceptable. She was taken out of her class and trained to be righted. The procedure somehow granted her the ability to write inverse or reverse or the combination of the two. No one ever borrowed her class notes from lectures more than once. Did you experience something like this or is it just a left handed thing?

• Great video 🙂

• Make videos on sector area

• Are you single?….

• shes so hot tho

• Holds phone in right hand… writes with left hand… vid must be flipped 😂… however which one is flipped? This vid or all of the tutorials!?

• Thank you very much, I just passed because of you

• can you do a video on how to take antilog ? would be useful for physics problems

• 👍🏼

• Oh, Nancy you are gorgeous.

• Hey Nancy how do we calculate regression and correlation?

• Are you married? Do you have kids? Would you marry me?

• I’ll be your friend in the east coast and who doesn’t love Pasta plus I appreciate all the times you have help me with math watching your videos lol

• I’m Not Letting You Go This Time

• HOW CAN I PROVE MATHMATICALLY THAT ab>a+b for all a and b
?

• I’m so happy you are back! Thank’s for all the help!

• THE ONLY REASON THAT BROUGHT ME HERE IS TO KNOW HOW YOU WRITE LIKE THAT BUT…. :,(

• Rakan KF lol she just writes normally and flips her video along the y-axis

• Teach a man to fish and he’ll sit in a boat all day and drink beer.

• IIT exams are a way much very very difficult than getting into mit , sundar pichai is a student of iit

• Im from the east coast and make some great pasta:)

• tbhhhhh i really just came for the teacher

• wtf is wrong with you no one asked

• I share your math instruction with many students and parents.

• Computer Science? Please do some programming videos! Especially ones with Linux

• Hi Nancy, How do stay mathematically motivated, and what inspires you to do it ?

• 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♥
Love you♥

• So, In this video I observed that you are right-handed not lift-handed like other videos… you mirrored the video itself…..I love you, Genius girl…..Thank you, video♥

• She uses to write on glass which is placed in front of the camera

• #teach set theory,Relations and function please nancy 🤗

• She writes on glass then mirrors the video

• Yup lol

• I’m guessing how she writes backwards is that she doesn’t. She writes normally and flips it to a mirror image when they’re editing.

• I Like You 😍

• i hate you

• Nancy when is your birthday ?

• Nancy what do you do other than making math videos for YT i mean your profession ?

• How can somebody soo beautiful be soo smart. You got it all gurl.

• NancyMagic videos btw.what about more basics for middle /high school

• special favourcan you prove 1/n diverges n ->infinity(you gather terms and prove that the groups are greater than another div. series )Ta!Chris

• Is it possible to write the formula for the area of a circle as a combination of identities, do an algebraic rewrite to get a function of two variables diameter and circumference then use integration to get back to the area formula? I was thinking maybe chain rule or quotient rule I don’t know but I thought it was an interesting problem I wanted to get a mathematicians perspective the math tutors at my school won’t answer this question.

• What I meant was how does one go about deriving the formula for the area of a circle by using integration? My mistake was, starting with the area of a circle formula and solving with integration discretely instead of using the standard equation of a circle and working through the problem that way.

• Nancy love ur nerdy jokes. Thanks for ur uploads. Entertaining AF.

• I was wondering if you can show how to apply calculus in real life? I know its really powerful and awesome, but i just cant wrap my head around how they choose what function for what. Does my question make any sense?

• I think she is using a mirror to write backwards (the video in mirror is being recorded as opposed to the board).

• Please explain some general proofs like Mean value Theorem

• What did you study at MIT? (I guess you say majors(?) in the states)

• If not only living off youtube, what other job do you have?

• If you can’t figure out how she “writes backward” by yourselves then you should probably stop wasting your time watching maths videos.

• yeah Nancy I have a question how does one get passionate about math

• This isn’t a math related question but do you cook or eat outside?

• Hello Nancy. Hello all. Help. I want to start/return to maths as a hobby – say spend about 1.5 hrs a day for the next few years. The aim is to self teach and practice and improve my knowledge from basic maths knowledge to post graduate level maths. So therefore 2 questions. 1. Is this possible with determination. And. 2. What order of maths methods would you recommend I follow that would form a natural progression? Say algebra to derivatives to … etc. Thanks

• I came for the math… I stayed for the mutual love of pasta 🍝

• I m also watching this for asmr

• I just discovered your channel and haven’t yet watched most of your videos, but you kind of strike me as the type of person that’s naturally good at explaining science to the general public. I think you should consider doing videos where you explain the surprising applications of math in the real world (if you’ve seen Hanna Fry’s videos/talks, you know what I mean)

• What happened to mathbff channel?

• Where abouts are you from?

• 2:40. I did my friends homework, I just charged them. Math killed them in college but hey I got the extra practice and got paid. HA!

• in my college days, I was taking my calculus final and my friend was across from me. I finished the test pretty fast. My friend looked at me with that “i have no idea how to do any of these problems help me” so when the teacher walked out he passed me he’s test and I did it for him. I didn’t care, we where engineering majors, I figured he would just drop out later (he did).

• How does she write backwards?

she has a transparent glass in front of her. she writes on it normally. the camera is behind the glass board. the camera sees the writing from behind. if you see the original video directly recorded from the camera, the writing would be mirrored, the writing would go from right to left. after she records everything, she takes it to a computer, and a software mirrors the video. so the image you see of her now in the video, is not what you’d see if she was in front of you in real life. but this is a mirrored image of her. notice in the other videos that she’s writing with her left hand in the video. in reality, she’s just right handed. in the other videos, her hair style, the splitting line in her hair is on the left. usually when people are standing in front of you in real life, the hair line split is on your right side (left side of the person with the hair). in this Q&A video her hair split line is on the right side. the videos are obviously edited, cuz she does that “fast forward” effect, and there are some cuts in the video. i’m amazed how people keep asking the same question.

• I can do everything except for translation English to algebra. I hate english.

• she’s not really writing backward.

• I don’t understand why 1+1 is 2 instead of 11.

• To get the writing right, just create a video mirror image of the writing (sorry for giving away the “secret” lol) One doesn’t notice Nancy being a mirror image (apart that she is not left handed), but makes a pleasant difference to the writing. (notice that Nancy is right handed on this video, but left handed when writing on the glass screen)

• Hello NancyPi, I love your videos! I actually took a lot of math classes in college and am not watching for homework help – but because I am a nerd …. and it is relaxing watching someone do math. Lol. It is a way to kinda remember it after college and learn new tricks I didn’t know before.

I would love if you did differential equations, partial differential equations, differential geometry, etc. The higher, even more fun math. <3 Those are the most interesting classes. I know less people are wanting to watch those compared to those people wanting trig and basic calc help "just to get through school" but I would love to watch higher math if you ever had time to make those videos as well!

Also - you casually mentioned your interest in math and comp sci - what did you actually get a formal degree in? What level degree did you get? I wanted to go to MIT back in the day but couldn't afford it. PROPS Girl! 🙂 Keep up the great videos.

• My heart started to beat again, Thank you!

• Just wanted to say that your work is really easy to understand,thankyou for that,i even figured out how you write backwards. Anyways,my question would be: Would you ever go into more detail for each year for students?

• you look so hot

• fuk u

• Any chance you could get to do math lecture on twitch…

• And can u teach us metrices please

• Do you have a boyfriend?

• stfu what if i asked that question

• I eat pasta for breakfast, lunch and dinner !!! 😲

• I wanted to learn math. Now I don’t. All guys here know why.

• It’s obvious, the picture is mirrored. Look at her hair line.

• Dear Nancy- I have struggled with math at times through my life. A good teacher can make a world of difference to a student beyond the subject. My math tutor set me on the road to a better future, and I am grateful for him every day.

• If you want to know how she writes backwards.She writes forward and after the video she flips it

• And I am a nerd so uhh…u ain’t puttin me to sleep

• Can you make videos about Boundary problems if you haven’t done so already? Distinct Real Roots. Equal Real Roots. Complex Conjugate Roots. Thanks! You’re incredible at explaining math. I tell everyone about your videos.

• Hello, Nancy! I am an incoming freshman in college, pursuing engineering. Ever since I was in middle school up to high school, I was already the “mathematician” or like the “math wizard” of the whole class. You just made me like math more.

I really appreciate all your videos, especially those of calculus 💖 really needed it. Can you make a video that has, like umm practice problems or applications of limits, derivatives and integrals? And then a solution after a few moments? It would really be of great help. If not, it’s fine. I still idolize and salute you! 💕

• You could be an actress or model you’re so smart and beautiful. Awesome teacher ☺️

• She just changes the camera to make the words from back

• Just when I am about point out your backward writing on another of your videos, here you are having a QnA and first question Boom ! 😄

• I am a dirty old man.

• After watching so many of your videos, I watched this and for some reason you looked slightly different to me, I couldn’t quite put my finger on it. Then i realized it’s because all your regular math videos are mirrored… so this is the first time i saw the true you, so to speak 😀

• Hey, Nancy can you please teach GCSE and A-level maths on your channel. Please help student who either taking GCSE or A-level maths exams, if you live in the UK

• Hint about Nancy writing backwards: She’s right-handed.

• @Mr Gardner’s Primary Education Video is actually sequence of images. So, they record a video and perform “horizontal image flipping” on every single image 🙂

• Sherzod Nurullayev so no glass is involved?

• @Mr Gardner’s Primary Education There is both. First she wrote on glass, and then they used “horizontal image flipping” 🙂

• It’s a lightboard and she is flipping the video during editing

• Common guys no need for hints it’s called a lighthouse studio.she is not the only one doing it

• I love in South Africa, so a bit far away. Also, I do like pasta, no you can’t have any.

• Hint about Nancy writing backwards: Check where her hair divides in this video compared to the regular ones.

• I can teach how she rights backwards.

• hey guys, can someone please tell me what happen to the old videos, i took a math class back in 2015 and i remember Nancy had more content on the Math Bff channel, but now i cant find them. i am just wondering what happen

• In Soviet Russia Math Do You

• Are you single? I am also a mathematician.

• shut up

• I am in love 😙😍 with this teacher 😘😘😘

• Samaj Gaya q itna love aaraha hai 😉😏😏😏

• disgusting

• Professora linda demais.

• Why u speak so nervously???

• Do you get paid to do math videos on youtube?

• Nancy you are so beautiful and adorable

• u weird as fuk

• I like chatting with you

• You guys should be a little more respectful AND show her your support through her Patreon link!!!

• How do not fall in love with this girl? Nancy, your classes are delicious to wacth, even for those not addicted in math. I think that is delicious listen to you talking about anything.

• Or she uses mirror !

• You speak Spanish ? . If yes, you could put a channel in Spanish?

• What happened to MathBFF?

• Try an IIT paper lol…

• I’m attracted to you……….

Alright have a good day, ttyl

• Mama! I love nerds

• HI Nancy can you do a video about abstract algebra?. About mapping I really want to learn it but I don`t understand some of the topic.

• College is hard. So glad I graduated before I burned out.

• Pretty, sweet and smart, you are the perfect woman.

• weird!!!!

• You are so sexy

• stop just stop

• How you writing like thiss

• answer to question one, are nancy´s videos mirrored 🤔

• How to magically write backwards: Draw on a tablet, reverse, mask and add as a new layer on top of your footage

• I have a multiplying polynomials Common Core Algebra 1 question for you. How do I write (x+3)(x-2)(x-8) in polynomial standard form?

• Pasta will have to be shared… but yes…

• i love pasta…..have you tried Michael’s of Brooklyn spaghetti sauce??? my favorite ,,,, and the part of yore hair is on the wrong side….why is it on one side when you are writing backwards….but on the other side when you are not ???? i am so so so disappointed that you are not really left handed

• As a calculus lecturer, I find many of my students had problem to work out the limits of f(x)=1/x (in x=0+, x=0-, x=+infty etc) using the epsilon-delta definition. Could you make a video about it so I will have an on-line tutorial to refer them to?

• Thanks Teacher ❤

• take of the heart emoji off now

• Now writing in reverse is not a secret, you are just using a mirrored version of your video, because you are a right handed and the videos show a left handed image, nevertheless, you are doing great, I like your lectures a lot.

• You don’t wright backwards you use camera tricks.

• I must apologize in advance for finding you completely transcendental.

• hard work pays off congrats. math and pasta are awesome!

• Here’s a hint to how she writes backwards, look which side she parts her hair in the Q&A vs her normal videos…

• I love your videos maam. Im a filipino math teacher. And i learned more from your video.. I hope i would see you. 😊

• Ur real Beautiful

• “linear control systems” can you teach us please

• With your speech, you have a soft voice. Since I have a hearing loss, I decrease the treble while increasing the bass. 🙂

• I like your talking methods.

• Partial derivatives, please. And get yourself an account on Patreon, so that we can support your work.

• She manages to write backwards by mirroring the image after recording 🙂

• Im here for math asmr

• How could she write in 0 gravity or on air? Wooooh….Wich

• 😂😂😂😂😂😂😂

• Answer to the first question: She writes normal and when the video is shot everything is backwards, Nancy is also on the right side of the screen. The. The video gets edited and a mirror or invert effect is applied. Very simple.

• Nancy pi: hey viewers,,u don’t need to like math
Viewers: so?
Nancy pi: just like me..and watch 😀
(Like if u agree) (thnx Nancy for helping us)

• But I know Nancy , you are actually righty . . In your videos you are actually mirroring 😉

• Please make video on counting of triangle (reasoning)

• The technology is a lightboard. You can find out information about how lightboards work (and how to build your own) here: @t. The technology used in the MIT Lightboard interactively flips the image and adds auxiliary images and video inputs into the captured video in real time, so that the instructor can immediately review the footage.

• do math games or math-offs if that makes sense.

• I don’t want to steal you writing bit, BUT I DO want that gradual speeding up and slowing down effect, with the tape winding sound! Is that Classified as well? Oh and thanks for all the math and junk 😉 Your lessons are on point, GG!

• Lol…I love you nancy!you’re pretty beautiful….

• would you say i love you to your math teacher??

• What do you call a pretty girl on MIT campus…..lost!
don’t actually mean that.
Eileen Perez writes backwards also.

• Well that was wonderful. I wished that I had worked my blank off to. So what was the motivation to work so hard in high school?

• next Q&A: what’s you zodiac sign?

• The beautiful girl I have ever seen.Can we be friends?

• I know How you don’t write backwards. LOL

• you should honestly just start a yt channel aside from math idk your choice haha

btw loved the vid!

• about writing backwards…….In videos where you don’t use the transparent board, your hair partition is on the right side. In the videos that you use the transparent board your hair partition is on the left side.
So I think that you use a mirror for your tutorials right?

• The truth is that you are not writing backwards, and that you are right handed. Clever technological trickery is used. Behind you is a white painted wall or plain backlight panel, using non-glossy flat paint. In front of you is a clear glass panel that works functionally like a white board. What the video cameras will see the writing in total reverse. There is a switch option either on the camera itself or on the video switcher board to mirror reverse the image. Such a reverse switch is useful for photography studios to allow the talent to preview him/herself, but for convenience in appearance touch up the mirror switch option is used before recording.

• Would u do a video on LACA please? (linear algebra and complex analysis)

• Hello ma’am.
I have a question about the graph. I need to know how many ways exist to calculate “total Depth” and and “mean depth in a graph. ( I need to know that because as I know there are many ways to calculate Integration ( an Important filed of SpaceSytnax, a theory which is based on the theory of graph). we have different integration such as Integration Telk- P-value – HH (Hellier and Hansen) and…
I need to know how we can calculate them
another filed that we calculate in SpaceSyntax is choice.
how we can calculate choice? ( thank god we have only one kind choice )

• So the truth 😂 comes out.lol your a natural born nerd some of us must work at it.😎🤔

• You write normal on the glass board, but you flip it on the camera

• @fireant G She writes on a glass and then flips (mirror) the video!

• What is the difference between a Rieman and Lebesque integral?

• Hi can I ask u?from where plz

• hi nancy your are the my , pet, beauty queen😍 real teacher
this 10th i have my 1st ca test of my basic mathematics course wish me !😘

• *she does not write backwards, she uses a mirror effect to be able to see it!*
You can tell at 3:40 when she writes with her right hand, on videos she writes with her left hand!

• Can you do a video on sigma notation? I wish I found your videos sooner!!

• she writes normally and it shows in the video as backwards and then she just flips the video 0:36

• Yup, you can see she’s right handed in this video and the others ‘left handed’ very cool style though, definitely unique

• Holy shit you flip the videos dont u & that’s how u write backwards so well!!!

• I didn’t see a video for oblique asymtotes
.

• Hey Nancy Pi! I recently started watching your maths video. Could you please provide some intuition on convolution, Laplace transform? Lots of Love from India!

• she doesn’t write backwards she’s not a lefty. she just flips the image

• You totally need to start doing asmr too. Its awesome. Asmr puts ypu to sleep if u want if not it just feels cool to listen.

• You r so beautiful’ smart’ and funny. You could do anything you wanted.

• Hi! Do you have or can you make videos on Combination and Permutation??

• shes not writing backwords i think she flips it while editing

• Give someone a fish, and he’ll eat it that day.
Teach them how to catch a fish, and they’ll never go hungry.

• Ok

• Can you do a video on Vectors please?!

• I live on the east coast (i.e. probably near you, if you still live within daily commuting distance of MIT) but you can’t have my pasta :0. Rather, I’ll buy you your own : )

• 0:36 about write backwards, just wanna give people a clue. 😉 Nancy use the right hand here , but in the videos she use left hand, ( if you people have just a little IQ you can find out how she can do it ) sorry Nancy , but nice trick

• was that Mathbff a contract channel, I mean some kinda contract to make videos for them. Or it was your own channel and you just changed it’s name?

• I know how you write…….
Mirror effect by camera recording…… although you write on transparent glass…..
Guys if you check this effect see video in normal mirror…….

• Do you work on Statistics?

• It’s all about math until math has plump lips and high cheekbones. Your voice is nicer than Veronica’s was, but she needed to be heard in a huge class room, and so I learned Trig. Richard, the visionary, said he didn’t think of trig and log functions as curves, but as the series that were expanded to evaluate them — a big help in finding their derivatives! I’ve subscribed so I can have a living reference to dust off my math skills. If you’ll come across the Basin some nice weekend I’ll give you a sailing lesson!

• Make videos about the history of math. Like how and why Isaac Newton invented the Calculus.

• Yes, yes, yes.

• 🤭🤭

• Hi nancy ma’am i am from india….am your student…you ‘re best.teacher.😘

• Answer to question 1: She doesn’t write backwards.. She writes on the board like one normally would, but the video is mirrored and therefore appears the correct way to viewers.

• Just come here to say thank you!!!
I’ve been watching your videos since high school. I struggled quite a bit back then, high school calculus and algebra was killing me. But glad I found your channel, your videos were super helpful! Now I just got 169 in qualitative section for GRE last week. I think of all the math courses I have to take from high school to college, you are definitely the greatest math instructor I had!

• Passando pra agradecer pelo ótimo trabalho!!! Seu canal é o melhor. Parabéns Nancy.

• The REAL question is: Do you have a boyfriend?

• Simp

• @Holly CT lol right

• @FrenkyB hahahahahaaa!!! the odds are stacked

• Yup

• FrenkyB Yes me

• she is not weiting backwards… she is actually writing with her right hand, the video is flipped horizontally🙂

• ASMR starts at 4:08! You’re welcome.

• Thank you for being so clear in speech and thought! I found you because I need to brush-up on my math. My 9-yr old daughter is very good with math and we constantly do skills that are far beyond 4th grade. We are just now starting quadratic expressions. I like that I can show her videos of a young woman doing math!

• will you marridin me nancy .ı love you

• Why are you so beautiful

• Is there any chronological order to you lessons?
I passed Trig in high school, but I don’t know how.
I would be interested in actually learning it.

• 🌹

• You are so beautiful ❤️❤️😘… Your smile just beautiful

• supposed to be studying for my calculus exam tomorrow but here i am watching your Q&A

• Please make a video on Long with cube roots and fractions in it. Also, what do you do for a living? Hoe Old are you? I also live in the east coast:)

• Nancy we need more geometry videos like transformations, Area and some word problems.

• Thank you i like your method dear

• Clear neat awesome…. you’re making me a genius thanks…

• lol

• Wow , I’ve been looking all over the interwebs for you !!!!! I fired up a Math BFF vid and said to myself : ” This is NOT Nancy …. I’m sure this Nancy (sorta’) look alike is a very nice person ; but ….. NOT Nancy !! “

• Your voice is amazing Nancy, can you do some asmr for brakes?

• Hey NancyPi, I love your videos. Could you remove your Q&A from your homepage? It plays every time I go to your page and was done a year ago. Your teaching style is perfect for me, please keep posting!

• 1:41 Wait say it again but more slowly…

Oops wrong joke

• would you introduce, how to create or generate an algorithms, like 101 type of thing, thank you really

• A lot of you have never talked to a girl before and it shows

• @Isaac Iraheta watch Elon musk’s next mission rather than wasting time by watching this sexy smart bade

• @MidName watch Elon musk’s next mission rather than wasting time by watching this sexy smart bade

• @Vsk watch Elon musk’s next mission rather than wasting time by watching this sexy smart bade

• @JL 350 watch Elon musk’s next mission rather than wasting time by watching this sexy smart bade

• @Nikola Tesla and Elon Musk at least she smart

• I always more or less understand the formula or theory of math chapter. But while solving problems I can’t solve some problems and it’s frustrating.
Any advices on that ? Because I’m not sure if for that I need to solve different types of problems more?
Gimme some idea.

• I’ve watched many good instruction videos on subjects, but you have a profound quality for relating intimidating subject material very well. You inspire….
Thanks for the help.

• The only way maths can be interesting..

• smh

• reverse trick

• Appreciate the math help (I mean all of us do) but would you like to do calc work that’d be really great tbh and you should vlog for sum reason idk like a non math :”’))) I’d Sub fs

• Omg nancy! I found you! I loved your videos, they helped me so much 😊

• Wait if you also took computer science you can also code. Would love to see you make a video about programming tutorials ☺

• Mam are you mit Grad

• ASMR PLZZZ

• I want to your friend

• Can you do another Q & A?!?

• Teach us some Matlab or other IT tools

• 1:41 man that was hot hahaha

• stfu there are other websites for hornyness

• Your professionalism is respectable. Instead of making tiktok videos or showing off on IG, you’re helping idiots like me. Keep up the good work

• Hello. I have a question. How to integrate ln(sinx). Prounounced as natural log of sine x.

• If y’all are wondering how she writes backwards it’s just a mirror effect on the entire frame. You can tell because her hair is opposite in this video as compared to her other math videos

• she doesn’t write backward, the video mirrored

• hi nancy gosh ur so beautiful and your voice is so demure Iloveyou 😉

• I love love love love love love love you please marry me

• Ms. Pi 🙂 Thank you for all your videos. The way you express your self is so logically clear, always, you make math beautiful 🙂

• She writes on mirror

• For the writing skills
What she is actually doing is writing in front of a big glass and then have the camera record from the front of the glass. After the record she then uses software to mirror the video looking as if she is writing backward

• chukwuemeka okafor This makes actual sense, and is smart as heck too

• Guys her secret of writing backwards is: mirroring the video in post

• How did you get the nick name NancyPi?? Very clever…

• Have you ever thought of Goldbach’s hypothesis as the sides of a triangle divided into two parts?

• Totally one of my favourite math channels. Good job and thanks Nancy. You haven’t posted in a while but you have lots of useful videos up already! I used your videos as I was doing a bunch of upgrading. Now its calculus and Fourier haha.HAPPY NEW YEAR

• Who else cringed when she told it was magic writing backward?

• Nancy is the most beautiful Mathematician I’ve ever known 🥰

• First question easy answer: you are righty, everyone can see in the way you use your phone and write in the air, in the videos you are lefty, video edition “turn video horizontal”.

• conclusion: you can blame bullshit if you don’t get into your college

• Can you teach physics i must me veiwing

• And live streams

• Girl girl girl girl girl girl girl girl girl girl girl girl girl girl girl girl girl girl girl girl girl girl girl girl girl girl girl girl girl girl girl girl girl girl girl girl girl girl girl girl girl girl girl girl girl girl girl girl girl girl girl girl girl girl girl girl girl girl girl girl girl girl girl girl girl girl girl girl girl girl girl girl girl girl girl girl girl girl girl girl girl girl girl girl girl girl girl girl girl girl girl girl girl girl girl girl girl girl girl girl girl girl girl girl girl girl girl girl girl girl girl girl girl girl girl girl girl girl girl girl girl girl girl girl girl girl girl girl girl girl girl girl girl girl girl girl girl girl girl girl girl girl girl girl girl girl girl girl girl girl girl girl girl girl girl girl girl girl girl girl girl girl girl girl girl girl girl girl girl girl girl girl girl girl girl girl girl girl girl girl girl girl girl girl girl girl girl girl girl girl girl girl girl girl girl girl girl girl girl girl girl

• dummy!!!!, your probably a 12 year old

• she actually seem cool in person – the math personality is meh – but its nice to have personality. but its also very cool how intelligent she is – i mean that’s undoubtedly one of the best qualities a person can have esp when applied to educating others too. shes pretty awesome

like :
x^2+y^2+2gx+2fy+c=0

• Thanks mam i get help from your videos

• Writing backwards is easy, you need to know the secrets of editing. 🙂 The same question would be, are you left-handed?

• @kiran rao Thanks Sri for that.

• Ok frank..🙄🙄😁😀

• Eres un bon bon.

• Answer for the 1st question: She is using “Horizontal image flipping”

• She probally just looks into a mirror behind the camera, that would do it right

• Have you always lived in MA or did you move from out of state to goto MIT? Or did you attend via remote location? Thanks.

• Could you make a trig video (adding and multiplying vectors)? And could you do a multi part video on translating algebraic formulas? More Calc videos would be awesome too.

• I can write backwards, but not as fast as you. I think there is some trickery involved in what you do.

• You are high profile teacher.where country u belongs mam

• Hey Nancy, you’re due for another Q&A! So I’d like to know, in addition to teaching here, how do you use those awesome maff skills professionally? Thanks!

• yeah, i was wondering exactly that.

• Doing God’s work! Thanks for all your help. I’m using your videos to help me with my business level math class. I was in the military for many years and am doing school again and had many doubts about picking up a calculator again, but these videos really help me. I’m currently on derivatives and you explain things 10x better than my more than annoyed math professor. I ask him fairly obvious questions and he always tells me, “you should have learned it already” and he doesn’t understand and seems to treat me like I’m just another 19 year old who plays on his phone in class. I actually really want to get through school to get my Information Systems degree, but professors aren’t always sympathetic or helpful to people who aren’t very quick studies. Thanks for explaining the small things and catering to us dumb people!

• 😍 your maths videos from India

• you probably l like her for her looks weirdo

• A ten years old kid asking her “do we can be friends?” Then this young teacher say yes, we can be friends. The reactions of the kid and his friends is YESS!! WE DID IT!!

• Q: Why don’t you put link to your patreon on your older videos description box, and your website? I stumbled on your channel because I was looking for a good explanation of chain rule and youtube suggested me your video from 2018,and by the near end of it I was so pleased that I started to look for it, I took me a while before I have finally found it here. If it is about time then maybe you could delegate it to someone or write a python script that would do it for you? 😉

• Here is the math question:
How do you prove the equation : Sample standard deviation = s = sqrt [ Σ ( xi – x )2 / ( n – 1 ) ] ?
Why isn’t it divided by n, instead of (n-1) ?

• I am a boy of 11 years but then also why am I watching it at 1:00 at night..

• You R very honey

• Question one’s answer is obvious, she flips the video lol

• *Cringy*

• dawg you got some weird ass mfs in your comments watch out man

• When you realise that she uses ‘mirror ‘ editing..😑

• She obviously doesn’t edit her own video

• brain: i’m here for math ben. focus.
also brain: i guess i could “learn” a bit more

• uh oh another parasocial relationship

• Who’s ur bf?

• Q&A is kinda hot

• You write forwards and mirror the footage so it appears forward to us.

• Maths or your passions? Which one is more important for you?

• How can I learn calculous ?
Do I read a book ?
Which book do I read ?

• God, you are so sweet. Thanks for helping me through the math exam 🙂

• Marija Kero also writes backwards. You both are amazing.

• حلوة

• Hi, you very amazing. and very nice and cuteeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeee.

• My dear math teacher I wans to meet you… How’s that possible????

• Who is watching this in 2020 ?

• Ma soeur nancy
Pour quoi on a choisie le cercle 360 degre?

• Uh have became a good teacher in mathematics

• The “trick” is: She writes normally on the glass and then, on the edition tool, she/the editor flips the video horizontally.

• Nancy must have been the most popular girl at MIT…
but she was surrounded by guys that had no idea how to please her.

• Just smile and talk

• I have some problems in differential equations
How can I send u pics of those problems?

• Dream girl for sure.

• 0:37 All she does is write normal and then when she edits the video she just uses the flip tool to flip the video so everything on the left side is on the right and everything on the right side is on the left

• Teacher Nancy : Tell me the easiest way to learn Math and how did you learned it . Thx 💙

• ‘Cause I really trying for understanding math’s lessons so I will be happy and will be so great if you thinking to help me 😥

• ohhh my crush <3

• I know the answer to the first question, and she’s really smart

• 1:41 I love that🔞

• Obviously you have a large mirror in front of the glass you write on, apart from the fact that beauty and brains being a lethal combination…well at least distracting.

• she writes normally but the editor just flips the video

• “Super passionate about maths”, I feel you Sister. We are of the same tribe.

• 0:35 I actually beated the riddle, she doesn’t even write backwards, what she does is that she write normally on the transparent board, making the words come out mirrored from their original form (mirrored to the camera aka what we see and normal to her) then she mirrors the entire video with an editing software. I. AM. A. GENIUS. PLACE ME NEXT TO NEWTON.

• I think you donot write Backwards. It’s your camera which just invert your writing to make it correct. You are using Selfi mode. May be .

• what is the meaning of Nancy

• She writes on glass, then mirrors it. 😜 Linear Algebra taught me that. 😂

• Sri Raj Nancy was the first, that I’ve seen, to do this. Blew my mind. 😂

• there is nothing secret involved in it check out the following link for reference: link 1:

• Nancy is playing with fire . She thinks we are fools to think she is writing backwards. Shame on u nancy

• Why’s it been sooo long since your Last video…. I miss your explanations.

• She doesn’t write backwards, the video is only flipped horizontally

• v

• @kiran rao what do you mean

• @Ali Jaberits nothing ali jaber. i just wanna tell people the secret(magic) behind her left hand writing is “light board technology”.. thats it nothing serious.
have a nice day😁😁😊

• Plz make videos on multiple integrals

• Brains beauty with braces…

• You are a perfect example of beauty with brain ..😍

• She probably doesn’t write backwards… it’s called mirroring your videos.

• you are very beatyfull girl as well as talented

• llegue por accidente, no se todavia ingles, pero debo decir que esta chica es la mas preciosa que he visto a la hora de explicar matemáticas, espero siga haciendo contenido y se animen a aprender.

• the part in her hair is on the wrong side !!!!!

• I’ve a sad story. I used to watch Nancy’s videos for my calculus classes when I studied computer science. Then I changed my career to accounting, then I was suspended from school because I was lazy. A year later, I came back to college on summer 2019, but it wasn’t until today when I’m taking a class about calculus applications in business that I heard again from her.

• Please make more math videos! Like simplex method linear programming problems. I’m really stuck with it.

• You remind me a lot of Aubrey Plaza

• This women is very chill, beautiful and intelligent. And apart from being a good math teacher she is a wife materiel for sure.

• Nancy, how did you go about attending math lectures? Did you just sit and listen, or did you take notes? I get so lost when my lecturer talks, and then I end up youtubing everything. Just wondering if there was a way to optimize how I studied maths.

• Great 🙂

• I know how she writes backwards. She actually writes correctly but she flips the video so that all the letters would be correct for the viewers, if you know what I mean.

• Nacy, you can write what you want, you are the magician and thas all greetins from Mexico

• , certainly there is no secret for her writing. she was completely right handed there is technology called ” LIGHT BOARD TEACHING” GOOGLE the word now itself ..” LIGHT BOARD TEACHING”…..there is nothing secret involved in it check out the following link for reference: link 1:

• So how is life going for you

• Nancy how you write and it comes exactly clear

• love miss your explanation plz could do more about linear algebra …highly appreciate

• what? nobody ask a question if she’s married or have a boyfriend?😂😂😂

• I love how quirky you are

• You flip your videos, thats how you write backwards:) I just noticed your hairline change ONLY for this video:)

• Most beautiful and funny math teacher

• You are a great math teacher

• 3:06 “u give a man a vaghina he will schpich for a day, u teach a man how to use his hand as a vaghina he will schpich for a lifetime” – admiral general aladeen of wadiyah

• You’re not left-handed. The First Q&A

• l like you very much

• @ 2:43, why? LOL!

• I you give my mother a fish, today you eat fried fish, tomorrow fish soup and the day after fish croquettes.

• You ar so cute mam

• Look me up jef a carma

• Asmr please. That would be amazing!

• I got to MIT at 16 years old, but found it boring and moved on

• Humans are 60% water. No one drools after water do they?

• Euler wrote 800 pages of research per day equiv to 76 volumes of work.

• what happens to the bag on the left all the time… in, out, in, out…

• She can write backwards because of the camera flipping the video. You can tell by her hairline and her dominant hand motions.

• Your channel is amazing for a selftaught, chaotic type of guy like me. Thank you.

• Just now watching this. Do it again!!!! You seem smart enough to see through me and recognize the difference between a real person and someone trying to get a date. Do you ever wish you could find someone to talk to?

• Wow

• Are You vegan?

question for you – int- e^-x^2 dx or the gaussion integral

• I dont like maths but *I LIKE YOU*

• U would have to be stupid to not know how she writes ‘backwards’

• Selam chat iş your name best speeak oryli

• Biytful

• When she said “I busted my ass” I thought it was pretty hot

• too bad I did not have a teacher like you, might of made it through thermo…

• What is your “daytime job”?

• Hi Nancy! I love Mathematics and I love solving and analyzing problems. I am currently taking Computer Sciemce. I dont love it the way I love Mathematics. Could you give me some tips on how it can be more interesting? Thank you!

• Yes! I do love pasta and I’m good at cooking – they say. But unfortunately I don’t live on the East Coast : D
I kind of agree with the ASMR
hypothesis. But that doesn’t discount that you are actually great at explaining math. Thank you for your videos.

• I’m new to be in your chanal. Love your math teaching style. Thank you

• Question: can you do lectures on the mathematics of Wavelets Transforms ending with using Nurbs to develop a Wavelet?

I watch I’m Indian

• Question… Show us your best pasta recipy : )

• @NancyPi Math problem ideas: Maybe you could do some interesting and useful math in terms of bitcoin and blockchain. As a developer am interested in blockchain, but developers aren’t mathematicians, cause too much work for just one person, so I can’t do myself 😉

• The secret of you writing backward is that you are not! The set background is the pure white wall, in front of you and facing away from the white wall is a clear plexiglass glass or genuine glass wall that is readily erase able, and you are right handed. Everything becomes viewable by electronic right to left transformation!

• I do appreciate your math tutorials. They have helped me immensely.

• Why do I feel like she’s gonna start talking about a math equation.

• 0:50 she writes normally then mirrors the video

• love your vids Nancy. Dont know why i clicked but it was still entertaining 😉 thanks to your vids i managed to understand u sub! lol keep it up. your my first stop for anything math!!

• you are right-handed and write normal, but u have flipped the whole video 🤗

• Hi Nancy. I love your videos very much. I also make videos on maths. I am learning a lot from you

• Hi Nancy!!! 😍😍

• Nancy, were you the first to write “backwards” like a wizard? It’s a great idea. “Anyone can fish! It’s 2018.” Yes! Preach! And now it’s 2020 and COVID and your content is even more relevant. I link your videos often for my students since flipped classrooms works really well right now. I hope you get many likes and subs from my students. Thanks so much Nancy.

• Are you in MIT ???

• Nancy you’re so beautiful
with a good Explanation

• You look gorgeous, hot and beautiful.

• She looks different….. now that we arent looking at her mirrored🤣😅

• Would you marry me?

• excelente

• shes hot

• she doesn,t write backward, the trick is she writes on a glass normaly but then she puts the video mirroredly, she is pretty anyway

• Thank you for your work. You are brilliant.

• Every math question I wondered about was answered when you started twirling your hair. Seriously, it has nothing to do with math but about everything to do with you. You’re awesome!!!

• I broke up with my girlfriend when I realized what I had really been looking for….Maths

Maths = Nancy + Me

• do you solve gr 8 math help

• So you are specializied in computer science now? LOL AMAZING i must take your number hehehe

• Yeah, let’s be friends!!! I live in the eastern US coast and yes I love pasta and of course pizza. I was probably in the top 5 or 3 smartest kids for Alg 1, but then a stem test came and destroy my spirit (I was not so good at science neither at writing back then). But, well now I am just another student who loves math and also likes to get involved in many activities at school.

• I just realized…you are probably recording these videos writing with your right hand and writing forwards…then flipping the video in post production so that the text is not backwards to the viewer. Very clever. This would make you right handed, not left handed. I’m going to say this is confirmed as you air paint with your right hand in this video.

• OT: content suggestion: Discrete mathematics

• 4:28 the mic is nice… i didnt hope that hair sound would be audible
5:58 i dont know why i am laughing, a combination of relatability and sleep (ps: sleep is due to late night, not due to the voice)

• I live in the east coast, I love pasta, but I hate math. Can we still be friends?

• I freaking love your shyness..

• you are such a exquisite creature all you need to do is just talk so if the math does not get people your soft sexy voice certainly will.

• heyyyyy nancy !!!!! where do you live?? you are so sweet,cute and great mathematician…..

• Why does a math tutor have 1.3k comments….

• you just flip the video no magic trick

• My math abilities are almost nowhere! Do you think it’s possible for someone like me to turn that around?

• l like math……..and may it be possible to help me when i have some problems in math which are not there in your video channel?

• Are you a math teacher professionally, and if not, why not? You have a natural gift.

• Hi It’s Nancy… Hi Math Goddess, Hello from inside the great firewall

• i can do backwards righting too heheeh

• You are a very beautiful and intelligent women. If you would be my wife, I would treat you like the Queen of the world. ♥️

• Where are you from nice teacher

• NAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAANNNNNNNNNNNNNNNNNCCCCCCCCCCCCCCCCCCCCCCCCYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYY

• Thanks, Nancy.

• Please do a video on series convergence

• GIVE ME A ❤️
I don’t know why it came to recommendation!🤔

• Hi, Nancy. What type of markers do you use ? Dont seem to be regular whiteboard markers.

• Hi Nancy! How i wish that your youtube channel existed when i was taking my math subjects during my college days… life would be easier 🥰

• Why the dislikes!?

• Mam Hindi m video

• Your videos are one of four I use to differentiate instruction with my students for alg I & II .
rob bob, khan and Patrick jmt are the others. . I try others but my students say they did not like them.

• i highly recommend you to solve jee advance 2019 maths paper plz solve you will have fun

• @Ayush Gautam 3299 yeah right I agreed but majority of the Indians nowadays hate maths they only do maths for Marks and blame goes to education system and society

• @Nikola Tesla and Elon Musk who told you

• @Nikola Tesla and Elon Musk I love math and all my friends love math you cannot judge a country by the the society that you live in .

• @Nikola Tesla and Elon Musk first of all I didn’t say her either u to do anything!! Don’t drag me in! But yeah some people here in India love maths and some don’t !!but majority don’t love to do maths !Being one of them!😂😂

• @Nikola Tesla and Elon Musk but I think that’s only true in the young generations!

• You are awesome!!!!!!!!!😊

• I’d like to request more videos on the study methods you used while at MIT. How many hours did you study per day and how to manage time/productivity tips?

• XD I know how you do it. I think I’ll copy your technique XD

• 😂 😂 😂

• Sexy, beautiful, and very intelligent.

• watch Elon musk’s next mission rather than wasting time by watching this sexy smart bade

• Q1. She just mirrors the video while processing.

• I love you so much, more than math!!! you are so nice + nice= beautiful. wish you + hope you = the best life and I do not know but you are a great person + nice look= funny
