Description: MIT grad shows how to simplify a rational expression. To skip ahead: 1) for how to simplify an expression with DIFFERENCE of SQUARES factoring in it (x^2 - 49), skip to time 1:01. 2) for how to write the CONDITION or RESTRICTION, skip to time 3:52. 3) for how to simplify an expression with QUADRATIC(s) in it (like the x^2 - 3x + 2 trinomial), skip to time 6:12. 4) for an example with LARGER COEFFICIENTS and a NEGATIVE x^2 term (like -20x^2 + 14x + 12), skip to time 9:57. Nancy formerly of mathbff explains the steps:

There are three steps to simplify algebraic rational expressions:
1) Factor the numerator and denominator as much as possible.
2) Cancel factors that are the same on top and bottom.
3) Write a restriction ("condition") for any x values that used to make the denominator zero, before you cancelled factors. For instance: "x cannot equal -1".
1) FACTOR as much as you can: Factor the top and bottom as much as possible. In both the numerator and denominator, always check first if there's a number or a variable (x) that is in all the terms that you can pull out front. If you have something that looks like "x^2 minus a perfect square number", like x^2 - 9, you can factor using the difference of squares formula, into (x + 3)(x - 3). If you have a difference of cubes (x^3 - 8) or sum of cubes (x^3 + 27), you can factor using the sum/difference of cubes formulas. If you have a quadratic expression on top or bottom that has three terms ("trinomial"), you can factor it using trial and error, or the "magic x" trick for factoring. To learn how to factor quadratics, check out my video on factoring.
2) CANCEL: Cross out any factors that are the same on top and bottom, and write what's left behind. When you've cancelled everything you can, you now have your simplified rational expression, or expression "reduced to lowest terms" or in "simplest form".
3) CONDITION: Is that all? To be technically correct, you should also write a note next to the simplified rational expression that states the restriction. You can check with your teacher to see if you’re required to write it for your class. But either way, the restriction is there, and the final answer isn’t really complete without this “condition”. All you need to do is: look at any factor(s) you cancelled in the denominator (ex: x-7), see what x value used to make that factor equal to zero (7), and next to your answer write “x not equal to” that number (x not equal to 7).
We put the restriction, or condition, there at the end, because if we didn’t, the restricted x value would appear to be a valid x value for the expression, when it’s not. When we simplified the expression by cancelling the bottom factor, we got rid of the undefined, division-by-zero problem for that x-value, but in reality that x-value is still not allowed. So to be totally correct, write the note that states this restriction next to your answer.

first to comment….. Great video…..This is very helping…..
Lol I’m a 12th grade student still I watched the full video. Good stuff!
Which grade is this for?
yeah which grade is this for son give the lady an answer
I love it! ❤ A hug from Brazil, Nancy.
You are back!!
#RIPX
You’re a natural educator.
Motorola Nova … and rational.
Mama
It’s easy, it really helps in Intergration specially in partial fraction !
Thanks for coming back Nancy! I found your calc lectures really helpful
Jerry’s Studio agreed!
just here to support <3
I’m glad you are still making videos, the new girl on MathBFF is alright but she is no NancyPi.
William Nield ur right
I love you Nancy
Very use full Nancy …👍👍❤
Can u do a video about 3d curl?
Thank you.
I really love ur videos, great job keep it up REEEEEEEEEEEEEEEEEEEEEEEE
Awesome ✔✔👍👍👌👌
Question Nancy…wouldn’t you always want to remove the “x” from the denominator…or is that just in Calculus?
you are back ! .. and i love it <3
Hi Nancy, I am looking for more advance calculus videos, do you know any channel about it? Thanks a lot… great vidios, way to go.
I rather watch this than the world cup.
Same. 😀
lololol
wo wo wo wo really???? well yea u right.
Great! More videos like this!
You’ll always be my math bff <3
So fine
Hi Nancy, thanks for the great video. I am having trouble with factoring the final example when you get (5x-6)(3x+2). Do you know wher I am going wrong or where to look for assistance
Do some Calc! I’m struggling with related rates 🙁 💓
I love Nancy Pi. Thanks for all the great videos
Thank you, honestly i can’t believe how much you’ve helped me i passed so easily with your help
done with math for now… still watching lol
@Cassi Nova lmaoo
wtf
I got more video in my channel if you’re looking for more to binge watch 👀
@Franck’s Notes stfu
@Rizzo bruh
Yeah , I wanted to be done at 4:00, and Yeah, I know you want a good nights sleep, so Yeah,,, We both have to do the right thing.
Thanks for helping prevent summer slide on my math skills!
Good
Hellooooooooooooooooooo Nancy! I missed you 🙁 XD. I love your videos. You are the best 😉 :*
Can you put back the Magic X video on factoring. It was fantastic.
Nancy!
Your videos have really become much more funny over the year. I like your humor
I already have all my math units completed, why am I still watching this?
you conciser them Rational obversely I need hours and hours of readjustments
great job, greetings from Mexico
Im so glad you make videos! I would honestly not have passed pre-calc if it wasnt for your vids.
another great vid Nancy thank you. i have been watching you videos for years now and i have to say this is the happiest i have ever seen you in one. thanks for helping me pass calculas this past term. please keep’em coming. thank you
Thank you Nancy! Would have never succeeded in calculus without your videos, keep up the great work!
Do calc 2 videos!!
NANCY! YES!
JABRILS! 🙋🏻
But Whyyyyyyyyyyyyyy?????????
I try to understand but just can’t. its like when Seinfeld went out with newmans x
removable singularities? is it permissible to let x=1 or x=7 because its usually in a limit where x is approaching but not equal to the number that makes the function undefined?
Big fan of your work!
My math bae 😀
It’s good to hear your voice again, Nancy! I love what you’ve done in the description, it’s like a typical math course session, and definitely more search engine friendly for struggling students. Someday your channel could be all a body needs to learn advanced math!
I do not understand how you factorize the terms ? Just guessing ? Why 5x-6 ? Just quessing ? Why not 5x-3 ?
You need to be a math teacher. You have a natural gift. You not only show how you do the math, but you explain it very well so that you understand how to rationalize the steps though the problem.
You got me
Through trig and calculus! Thank you!!
Thank you ma’am!!!
Yesss I love you and your video 😘
I love her so much
Hı nancy , ı am a math teacher , could you explain me , which system do you use to make videos,
Hi Nancy, could you please kindly let me know how/what you use to project the lessons when you write? Is it like a mirror whiteboard or how do you do it?
😍😁 awesome.
Thanks for teaching me how to simplify a rational expression.
Angel Nancy,
Why is 1/0 undefined? Please explain me.
2nd example contains a hole at X=1 and also there is another restriction at X=-6.
Nancy,Isn’t it?
GOOD NIGHT!
😊ヾ(@^▽^@)ノ
Hi @NancyPi, can you make video on definition of polynomial? i.e. what makes a algebraic express a polynomial.
I had no idea your original conditions still remain after simplification, I thought the purpose was to adjust the expression so that there would no longer be a condition!!! Thank you Nancy, i’m glad you’re back.
* and I’ve never seen this hilarious quirky side to you! 3:54 — love it.
“leave this here like it’s the whole story, fronting like its the same as this ((twitch)) -when its *not* .”
Can you do a video on delta epsilon proof
Can you please make video of integration with definition and integration as a are of curve. Plz Nancy
A couple of questions about the last example: Where does the -10 come from? Doesn’t -6+2=-4? How do you get -8 from that? Please forgive my ignorance—I REALLY struggle with math.
She factored out -2 from 20, giving negative -10
I didn’t watch, but -10 is the difference not the sum.
Hey can you use your maths to create a huge magnetic suit that would allow me to walk on the streets and suck up cars onto the suit.
i love nancy i wish i could be her friend
Babe i miss yoy so much
10% of my engineering degree is due to you. Thx
@Dejan Zajebancije I was never put into algebra 1 part2 nor algebra 2 or calculus in high-school. But senior year, I passed out of geometry and trig. So after being two/three years into my college career I am only now starting calculus after self-taught algebra starting from basic concept.
@Dejan Zajebancije Computers do the calculations related to bridges nowadays.
Thank you ma’am you helped me a lot cuz this is the only thing that I can easily understand cuz some of the others is hard so thank you ,you really help a lot
@Dejan Zajebancije xD
This is a very nice thing to say
Nancy you’re such an amazing teacher, I’ve never ever found explanations of maths concepts so engaging and accessible. Thank you so much!
Love the work. keep it nancy. You’re the best youtuber when it comes to teaching math.
thank you!! you are awsome
can you do a series of SAT Math problems.
TY NANCY
13:55 lol 😀
Where did you go? Took me years to find this new channel
this chick is so hot i cant focus
You deserves more views.
I mean absolutely no disrespect whatsoever, but I find myself watching your videos and learning math simply because I find you beautiful, enjoyable, intelligent, and engaging. Keep up the great work. You are an inspiration!!
OMG UR MAKING VIDEOS AGAIN BLESSSSSSSS
how does she writes it😂
she writes normally and then the image gets flipped
Fyi I wouldn’t ignore you 🙂.
You helped me tremendously through school. Just graduated this spring with a 3.97 Summa Cum Laude! Thanks for your great help! I recommend you to everyone I know that needs math help. You are awesome!
I love your videos……..all of them are amazing…….thanks a lot……..
Please do more integral videos I want to learn please
I would make a lustful, slightly misogynist remark for the sake of my immaturity and imminent procrastination to compensate for my only partially existing sex life, but I’ll just like and subscribe instead…
I am just flying through these math problems now!!! Thank you!
The maths is great, your personality is sweet… but I just can’t get over *how clean your glass is* .. I mean… its literally cleaner than my laptop screen. In fact..why is your voice so clear.. are you *behind* the glass? Or is there an edge that stops before it reaches you? I came with maths questions… but now… I just have a ton of questions and none of them are maths related, hahah
Ma’am can you please make a video about derivatives of trigonometric function and derivatives of inverse trigonometric functions
Good work Nancy!
beautiful and intelligent, perfect
i think i love math irrationally
you know Nancy I changed my name the guys. I know I’m just an old pervert but now I’m much better at math 😉
Too hot for a math teacher😍
I am self studying mathematics here and your videos are a goto resource for me as your ability to explain complex concepts simply, and your great conversational teaching style, really gets the idea across.
Thanks for all the help so far NacyPI
Thank you so much!
I can actually focus on my assignments more when I just listen to her voice in the background XD anybody else agree? So soothing….
How does-6 and 2 add to 8?
Doesnt she see what she writes backwards IM CONFUSED
Why is she so hot? I would be daydreaming the entire math period.
You pervert is
Not like she wants u wake up bruv
Cute & intelligent, with clarity & a simplified style, you should have taught ALL of my classes, even basketball practice, LOL,!!
Enjoyed this first video of yours regarding “rational expressions”. I hate algebra & really don’t see the need for it on a everyday basis but
it’s a graduation requirement, unfortunately. Thanks for your simplified & direct problem solving approach! I will watch your other videos!
Mmm. Talk that talk grl.
Got that brain.
The math instruction would be easier to focus on if you blocked your image from the video. I find you distracting.
I want to wash your videos even if I don’t know algebra. Pretty
Amazing help couldn’t figure it out until this vid 10 outa 10 math help
NANNCYYYY!!
hi why is it that 4b^2-2a can no longer simplified to 2b^2-a, when you can still divide it by 2???
Please stop with the sound effects.
I like it.
Watching Guys do math are so boring to learn off of ,,,but learning from you got my attention just don’t leave out any steps when writing it out 😘
What if you have a negative rational function that is on the numerator, not too sure, plz help
with the last example, how did you get the 6 and 2 in (5x-6)(3x+2)?? Don’t the two numbers have to equal 12 when multiplied and 8 when subtracted?…..so 6-2=4?….I’m confused…and it wouldn’t be 4 and 3 bc 4-3=1 and 12-1=11….
Exactly!!!
ok ALSO, on example 3, you “getting lucky” means you put (5x-6)(3x+2) in the correct order? I initially wrote it as
(5x+2) and (3x-6) and was wrong….
ALSO on example 3 LOL sorry, why did you choose 5 & 2 and not 10 & 1? what’s the process to figuring that out?
thank you so much you’re a great teacher! <3
She makes it easy to understand for me.
Who invited this?!? D;
If i had a hot math teacher like this i would never fail a fucking single class
If there was a way to metabolically encapsulate u, I’d gorge u down forever 😊😊
great
yo gcse math guys
Wish u were my teacher !
U da best nancy!!!
Nancy I like all your videos, you are very good.
I am in my third year of Electrical Engineering at ENMU, and I am watching this. Nancy makes Math fun. I could watch math for hours… I often refer to the video on Logs… we use Logs a lot.
Love your hair. Makes math more interesting, even a little exciting 😉
JS Ly 👀👀
my man ur a perv
Very nice and simple way of explaining. I am tempted to watch your videos because you are more pretty than the problems.
I love you
How is she writing backwards 😭
i think i’ve learned more from you and your videos than all my 21 years of math classes.
I’m in love
Thank you teacher!!!
you are very beautiful I love your voice
Please keep making these videos sharing your knowledge. Your awesome
I love you, you are great
Ok now my head hurts !
Thank you
Forgive me, but on the last one you can also do 15x and x which gives you 15x squared as well, HOW DO YOU KNOW WHICH ONE TO CHOOSE?!
-6 + 2 = -4 and -6 + 1 = – 5 for Q3) both multiply to get C term but do not add to B term. Tried to FOIL it as well but can’t
It is too cute to learn math from you. I have a difficulty to concentrate.
Left handed brains beautiful there’s one lucky ass guy out there
And I’m about to learn math again lol
Please make a video about Partial fraction. I love how clear you can explain things and make math lot easier for me 🙂
Wow – Thank you! I love your videos
Ur hot
i like how she can relate when math’s confusing LMAO HAHAHA
Who else is watching this before a test?
you are my favorite maths teacher
Ur so adorable!!! Thank u for teaching us ❤️
Thank you 😊
greatest time ever learning math!
Good for you old man
Thank you!
12:30 /6 and -2 don’t add up to -8? was that an error, and they were both supposed to be negative?
Yes I’m confused on this
Imo that works only if there is no coefficient before x. In the case you are talking about, we have 5x and 3x, which means that you have to check the answer by doing (5x*2)+(-6*3x)=10x-18x=-8x
how did you write those on screen?
daym you hot
Did u learn this in algebra
you are too beautiful
I cant listen, when you on my eyes
What does that mean pervert
I might need your help , Are you Avalible next Shark Week ?
I’m smitten. Nancy, you do a great job explaining math.
Complex fractions / rational…omg please help!
Your videos have really become much more funny over the year. I like your humor.
I love u nancy pi
dude, if you time jump in the description, you dont put a period after. It wont detect any time jumps. just do 3:14 not 3:14
(edit: totally kidding)
Omg yr left hand like me but I’m idiot in math
nice
good
Hi
Sorry…the voice is annoying
she’s pretty
Brains and beauty. Your skin is beautiful Nancy
Give me your skin
you saved a life today
Glooks Shordy 💯
Can’t get over the fact she’s writing backwards
please post more! you are a BIG help!!
I want to know how you write backwards and why that doesn’t make you a spawn of the devil.
your voice is a medicine to all my daily problems.
All I really want to know is how you’re writing backwards like that..
@lord leoo actually its a glass with her writing but in editing she flips the video horizontally
if thats what u meant by mirrored then im totally just dazed lol
Bro she is using something called a light board. After recording the video she only flips the image so it looks like she is writing backwards
She won’t tell u you dumbgirl
Probably on a wall?
Jesus. Smart and beautiful. Marry me please?
I like your teaching ,,
In calculus and up you have to define what set x is in, so might as well get into the habit writing the restrictions
Very useful video
Super
I understand now woah
Hey Nancy, you really help a lot, great videos!!
Nancy,, you look beautiful!!
Explicas muy bien. Gracias por tus videos !
Absolutely love your explanations. I learned all this 65 years ago; you’re a great refresher and you fill in a lot I never heard.
How old r u and why were u watching this…respect
@KOT3Q wow .. don’t think u should be asking … respect
@Eseel Alsammarraie fam im just interested into y someone would watch this after 65 years
@KOT3Q yea yea , I gettit .lol . im curious too
KOT3Q That’s easy to answer. You see when you get older or more mature, it’s important to keep the brain 🧠 healthy. So good health is good diet, exercise, maths and lots of making out. So in a nutshell, keep on living like a 20 year old till you drop.
Thanks this helped out now time to go show that final math exam who’s boss!
Good luck! Go get them As!
john fog Covid 19 joins the chat
Marriage material
I been enjoying your math videos, a great refresher and I sm learning something new
thank you so much, Nancy
No need to feel disturbed by her classic beauty; Nancy is an outlier on the bell curve of normalcy…..a brilliant woman having a face that would qualify as a perfect model for a Renaissance artist like Rafael…she doesn’t know it, which enhances her appeal…IMO.
Hello Nancy!
how can we use Magic X for (10x^2 -7x -6)? while we can’t multiply 1 & -6 for -60 that becomes from a*c [in ax^2 + bx + c] and add -6 & 1 for -7 it becomes from b [in ax^2 + bx + c]
I don’t undrestand :'(
Cant help wonder ? Depending on your answer ,if you have one,or respond, will become relative to me asking you another.
What were your thoughts , if any, regarding the non cloning theorem for teleportation, when you first observed that the answer to the theorem was claimed to be hidden from human knowledge ?
When she said “you don’t have to live like that”😂
what a beautiful teacher,,
Sample #3…. what is the rule for inserting the -6 with the (5x ) instead of the +2 ? Which would have been (5x+2)(3x-6).
Because developing (5x+2)(3x-6) the result is 15x^2-24x-12 which os different from 15x^2-8x-12 (original equation)
@Leonardo Miguel
Perfect, got it…. thanks
ik this is really dumb but can anyone further explain the factoring portion of the third pproblem
15x^2-8x-12 and how it factored to what Nancy got
or at least link a vid to help my dumb self?
Wow thank you . You made me forget I have a test on math
You have my full attention, pretty and smart young lady! 🤓
Ooh someone has a crush
No se como llegue aqui pero enseña muy bien la profesora
My aunt is a math grad from MIT, unfortunately I live on the other side of the country from her. For now, it’ll be NancyPi to help with math while getting my computer science degree. SERIOUSLY thanks for this! Only thing is, it seems my book asks the trick questions and videos go over the simple rational expressions. I under stand these but for some reason it’s hard when i get something like 5/x-3
Nice video. Hope to see more lectures.
Nancy, you had me at ‘You don’t have to live like that.’ <3
ETA: It's not true that x<>7 is required in Example 1 because there is not actually a singularity at x = 7. You know this (although a student at this level might not). Similarly with Examples 2 and 3. I think it’s true in general when you factor out a zero/zero binomial, as long as the surviving denominator doesn’t have a zero in the same place.
YOU ARE BIURIFUL NANCY
U r explanation so good madam
you must write formula a^2 -b^2 = (a+b)(a-b)
Plese uf you can talk slowly , it difficult to understand non natives of english
I love you Nancy
🤓
You’re awesome!
Thank you so much
hey I love your videos are you still making videos there really helpful
This was so helpful!!!! You are great! Thank you!
“You’re like, i don’t know you tell me.”.
Hahahahahahahaha. I love you Nancy.
Ilove vate mu expression
could you graph the original function ?
lol im in 6th grade and i understand all of this thanks to nancy
Heat equation and diff eq?
the third one has an oopsy in it … (-6+1 is not = to -7 ) its =–5 and ( -6+2 is -4 not -8 ) but any ways thanks for helping us ❤
I knew I wasn’t going crazy and wasnt the only one who saw that.
I was racking my brain how she got there lol.
You are a heaven sent!!! Love your videos!!
YOUR AWESOME
U r a god(ess) what my main land chinese teacher couldn’t do u did
I actually teach university math… and I still can’t stop watching her videos!
simple to simplify!!
What happend to the two?
I am sorry but in the last exercise you throw me out on the top simplification and the compositive quadrastic ….
I know you make this exercises with your eyes closed, but please why there is a ÷6 and -2 ; if you added is -4 not ÷8
you did great for the explanation
Nancy can you tell us few words on your background? Very good videos. Tks
13:07
I do not undrstand how she goes from 5x = 6 to x= 6/5?
She divided the x term and the 6 by 5 to allow a restriction to occur in simplest terms
@LopsidedEdits Thanks 🤙
Thank you very much you helped me a lot.
You explain this so much better then my teacher !! Thank you !
“Thank GOD”, thank you very much ☺️ You are VERY good 😎
Hi! Do you have any videos on combination and permutation?
This definitely helped. 😊
You remind me of Lana Del Rey… lol. Thank you for this video!
Whose that?
I chose the wrong major
10:40 ON THE TOP U CAN FACTOR 3….
You cant take 3 out of the 8
@Gustavo Nicasio yes you can, nancy tell him
Isn’t the first problem x not equal to -7?
Can you post a video on multiplying, dividing, adding, and subtracting rational expressions!
Hi NancyPi, thanks for your videos. I need a sol. Of an eq.
Could you find the value of X please in this eq. : sqrt(5-4x^2+8x)+sqrt(8x-4x^2)=9-8x+4x^2 .
Damn sexy
my favorite so far
WOW! She teaches this better then some teachers! 0.o
#nancypi you are the best, I understand every single video you upload. I have an A in math class because of you thank you! My teacher always complicates thing, and is not very clear.
Nanci Pi, MIT graduate, you’re smart and make Math beautiful just like you! You make math fun and doable. However, my son’s teacher will throw in exotic problems such as this: (2x-5)(x+3)/15-3x less or = 0. Where he has to graph the solution set and write it using interval notation. We have asked several people with our circle who are Math majors who get stumped because the haven’t had to do such problems in a long time.
Teachers like the one my son has give Math a sour taste for kids who are already struggling. What is most frustrating to my son is that the teachers seems to work the easier problem in class on the board, but leave the more difficult ones for homework. Isn’t the goal to win kids to Math? Thank you in advance for helping to sweeten things up a bit for my son and so many others. 🙏 😃
Signed,
A concerned, yet hopeful mom who wants her kids to love Math like you do! 🥰🤗❤️
I usually watch all my youtube videos on x2 speed so when i put it on normal after watching one already sped up, I realized how seductive her voice sounds lol. Random. helpful video though!
Thanks a lot Nancy pie.You are a Brilliant brilliant tutor.
thank you!
Why are people so gross
Please disable the comments…………………………
Who else have engineering math exam tomorrow?
Hey @nancypi, can you help my pass NES math304 test?
I am not confused anymore
Mire ha mi yo tengo halgo ke exponer sobre Hoyente ha distansia local interviene X X X cuantas mujer cuantas honbre (encuentro un misterio o paradoja univerasl y vamos ha Resolverlo cuanto antes mejor
I love u Nancy
I love you very much I want to be your friend
meow
Holy smokes
Mathematically, this Is extremely simple. But what does it represent? This NancyPi could easily be a model. Beautiful.
Math is one of the coolest inventions ever!
Who gassed u up
very nice
The reason I got into a selective school was 85% from these maths tutorials. Thank you so much!
I hope this isn’t a Friday night (it is) but remembering stuff like this helps with the other stuff that comes later. You’ll still need to know it.
I hate your voice
Bruh she has to write backwards on that clear board
Nancy are you writing backwards or is there something else involved? Can you answer this question once and for all? lol also thanks great vid!
9:55 wholesome moment
We do not really “cancel the factor”. Rather we multiply by 1/(x-1) in the numerator and in the denominator. By doing that nothing changes since it comes back to multiplying by 1, if the denominator is different from 0.
Exercise 3, x cannot equal -1/2 neither.
The ideal woman; beautiful and can teach me math.
Honestly, these video are brilliant.
Can you please make a video on solving rational equations 😫🙏🏼
This woman is smarter than me at my best.
I’m not simping, no cap.
thank u .. for the video
Me to Nancy: Wanna hangout tonight?
Nancy: 03:57
YES!! That was good! I love it. Take a like from me.
Nancy, I’m with Grover on the last problem. -6 +2= -4 not -8?
thanks you Nancy!!!
You are a great mathematician! You so fast at times it freaks me out! I’m older so I am just looking to re-fresh myself. You are an excellent teacher!!
Hy
your explanations are great !! I get the understanding ..thank you
Love ur video
Your explanation is great. The numerator is easy to factor. This how i will factor the numerator. Is (X+7)and (x_7) which is _49 For my denorminator. I will use. 2 and negative _ 7 and so forth to solve the denominator. My own short distance to solve that expression. Thank you my dear Nancy. Can you make video to work on. trynomo please. Your explanation is great trust me.
She look like a famous model
from heaven above
Ahh thank u! This helped A LOT 🙂
hey nancy i failed 5 times in math i dont know why i watched every single video of your classes any ways now im studying arts love your classes still
Nancy, you are the best. because of you, I got P for my math class.
im so confused
Nancy gorgeous maths teacher
i just noticed shes writing backwards… damn thats talent
I assume you are right handed and flip the video left right? Great sound effects!
Cancel a can?
That was very useful.
I don’t get what you do with -8 please
Can you do a video on adding and multiplying rational expressions?
Gracias por la información de la reducción buen método
so sweet
and pretty
0:22 oooo I think I heard some Nancy humor in there
Nancy in equation no. 3 how that -6+2=-8 ?
She has such a nice voice
Is having ure hears rightside a symbol for an obsessed clan/cult? Ouh goddamn u got busted by me. I am gonna send u an swat.
I’m gonna cry I’m so lost
