There's many reasons why someone would be watching math videos. But I will be giving one of the best reasons. Math is one of the best ways to give your brain a daily work out, which in return will cut your chances of being diagnosed with dementia or Alzheimer's by at least 30%.
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
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.
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!!
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!
Thank you for showing how you did the factoring! My teachers just skip over those details, and I have trouble factoring, and this helps me remember how to do it with different types of equations. Thanks!! These math videos are helping so much!
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!!
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!!

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!

Why do we not have to add our 2 factors to equal the middle term? The last simplification does not equal to -8x or -7x....first she says that we need to find two numbers that multiply that also add together to equal to the middle term...then in the last rational expression all we do is multiply and ignore that the two multiples do not add together to make the middle terms anymore...I am really confused and it hard to type out, but please anyone help me....we have (3x-6)(5x+2) which multiply to -12 but do not add to -8. What did I miss? please help!????!!
Oh my god I think the only reason I’m going to pass my precalc is because of these videos. You explain it very well, and with little humor breaks it keeps me paying attention. Thanks!

Watching this video and being able to keep up with the calculation I stumble upon why so many of us were so bad at math back when. I think the last time I did this stuff was circa 2002, and I remember it being oh so hard. The teacher walked us through a couple examples akin to problem 1 in this video- easy enough in class, even if you're new to these problems. Then we got the homework, which was 33% of our grade in that wretched year long class, and all the problems were akin to problem 3 in this video; the philosophy seemingly being "Well, if we show you how to work problems you won't develop logic. Instead of us teachers teaching you stuff, just use LOOOOOOOGIIIIIIIIIC!" If I recall my class of 25 had like 6-7 people who passed (barely in some of those cases) this section. I appreciate these videos, even now years later!

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
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! 🥰🤗❤️

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.
These video's help very much. ALL of this stuff are my favorites and lots of fun to play with. I still love math, even in my 60s. Love the video's, NancyPi!!! Thank you for re-kindling my interest in this always fun and fascinating subject!!! As NancyPi says, "Like & subscribe"!!! Highly recommended!!!

All I can think about is how she is writing backward for our benefit, since she's standing behind a clear writing surface
Bruh the screen is laterally inverted so we see the proper letters.
She just inverted the screen LMFAO

Always a relief to be able to pause, rewind and watch many times a video; instead of a real time class 🙄

Which grade is this for?

This is for grade 11 in New Zealand, about for 16 to 15 years old maths students NCEA level 1.
This would appear too simple to all the Indian students since they've been learning this in junior classes.
this is so basic if you are in college this is can t help youu

TIMING ( 12:23 - 12:30 ) she is writing -2 ( 5x -6 ) ( 2x +1 ) but if we look at it as she said in 2nd question, in this we should multiply 2 numbers to get -6 but also add them to get -7
it should be -6 and -1 because if we add them we gonna get -7 and if we multiply we gonna get -6...
but she didn't do that and it's quite confusing. in the 2nd question, she is telling us to do something but in the 3rd question, she isn't doing that....
