• First

• Omg 😍 yaaassss!

• YESSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSS Brilliant Brilliant Brilliant

• Dannky bhi!!!!

• Hello

• So freaking awesome!!!!

• math is about to get a lot hotter

• I got a lot shittier doing math 🙁

• She is more like my league

• Nancy Is the hot math tutor we never had

• i know right i’ d actually focus this time around 😉

• yes….and brains

• Good to see you back, your videos helped me through Calc I, II and Differential Equations. So thank you and I wish you the best with this channel:)

Dr peyam’s show.
blackpenredpen.
flammable maths.
PatrickJMT.
Krista king.

• Josue Becerra go to mathbff , she has a lot of calc. stuff there

• omg finally you came back !!! Your channel helped me a lot and I was waiting for you so far😭

• Hopefully the videos won’t be months apart!

• If you have a direction vector, and it represents a change of direction over a simple smooth curve. Take the derivative of it, and you’ll get the velocity vector. Divide the velocity vector by its magnitude and you’ll get the unit tangent vector. Take the derivative of the unit tangent vector, and divide it by the magnitude of the velocity vector, and that will represent the curvature of the direction vector. If you choose a circle, then r(t) = rcos(t) i + r sine(t) j.. Using that information, you should be able to derive the curvature of the circle which will be 1/r. Large circles have small curvatures; whereas, small ones have large curvatures. Certainly, a small circle will turn around much faster than a large one right? Ugh! What’s Multivariate Calculus? LOL

• You’re truly the best and your videos are extremely helpful, can’t wait.

• Stats

• hey queen welcome back!

• Yassss queeen

• We missed you so much!! Please come back soon!!!

• Can you make a video about parametric form?

• Welcome back, lomg time no see!!

• The savior has risen

• Awesome. I love Nancy. Nancy, Krista King and Patrickjmt are the best calculus teachers

• BTC is crashing, this is the best thing i’ve heard all day!

• My financials are screwed and I cant retire, but I agree.

• BTC is always crashing though

• Clemens Dotson If you can’t retire because of a temporary dip in BTC, you have way too aggressive of a portfolio.

• Nancy I just got a 💯 on my Calc test today thanks to your help with applications of derivatives and all that stuff! You’re the greatest 👍🏼

• NOt even in school anymore, but still watching.

• Lol

• Ruminating15 same here big fan of Nancy

• I am 60 and still interested.

• so i ooooo she’s cute

• I don’t know if I’m past the point in my education where you’re videos will be able to help, but you helped a ton when I was in calc.

• D S I just started calc earlier this month and she’s been a good help so far. Hopefully she’ll have something to supplement your needs.

• Yes, she is back!!!

• So happy you’re back!!! hope to see some linear algebra videos 🙂

• Nice to see you again! Happy New Year Nancy

• I love this channel. Its better so start with some algebra.

• Welcome Back! Thank You so much for all the help you gave me throughout my Calculus courses.

• Welcome back!

• Wasn’t this going to happen 8 months ago? What happened?

• you are smart and beautiful. are you married yet?

• ilysm

• Yay! Glad you’re back, today was my first day of cal 2!
Question tho, I thought your channel was Mathbff?? How come you’re not uploading there ? : o

• Ivonne The theory that many of her long time fans have come up with is that she was scared away by inappropriate pigs commenting in unfortunate ways.

• Michael MM oh no! I noticed some of the comments were gross, I’d be bothered by that too!

• Awesome!!! Glad you are back Nancy :)) couldn’t have gotten my A in Calculus without you and a few other great folks on here. You guys rock!!

• Missed you Nancy! Glad your back! You saved me and got me through algerbra 2 😛 One request I would have is maybe consider potentially making a video playlist specifically for targeting SAT common types or problems and how to tackle each the most effectively! I am sure plenty need help with those tests 😛 like myself!

• Thank you, Dharamveer! Which Calc 2 topics?

• NancyPi Partial fractions, trig substitutions, infinite series and sequences, polar coordinates.

• Best.Teacher.Ever.

• Nancy is the GOAT!

• yes finally

• She nos de wae, brothas.

• Do you have a math degree? I really need help with learning induction proofs for my computer science class.

• Physics. Very interesting…..which book do you use for that class?

• I’m a sophomore in High School, can you show me how to do partial differentiation? I know calculus pretty well!

• can you please do trigonometry??

• Yesssssssss🐶

• Holy shit, you’re alive.

• I love Mathbff channel and I wish to make a lot of lessons and thank you for Miss

• So nice to see you again!

• I now regret dropping math courses

• …And then she disappears again… To reappear in a year with another “nice to see you” -video with no background given. I do appreciate her videos, but it has been a little strange.

• The words you are looking for are the ones relating to “good luck “ and “welcome back “, liberally sprinkled with thanks for past assistance. I’m pretty sure she has a life and doesn’t owe us anything.

• I didn’t mean to be rude, but I am sure some of us have been somewhat confused/curious due to these different youtube accounts and a new partner, whom we ended up seeing pretty much in just a “trailer” and a “sample” video. I genuinely hope that Nancy is doing well and that NancyPi will take-off. With best wishes to her!

• everyoneelsegotthego: See, this is what I mean, now it has been a month…

• Shes back boys!!!

• Super excited and thankful to have you back!

• We’re glad you’re back sister 😀

• Could you please cover multivariable calculus

• Which topics are you thinking of?

• You’re amazing! With your help I was able to pass math and get my bachelor in Engineering. Now I’m doing my master and the math got a lot harder, will definitely keep an eye out on this channel! Again: THANK YOU!

• Ayeee

• Statistics please. Thank you. 👍

• Can you do questions related to permutations and combinations? Also how come you left Mathbff?

• Can you do chemistry?

• Can you do Discrete Mathematical topics? Thank You

• absolute best teacher ever

• Thanks you how you share mathematical knowledge, I am ever
happy to run your videos, because mathematics is a part of my life.

• 💛

• Welcome back Nancy 😀 Your videos really help I can’t wait for the new ones

• I always like touching base with my maths because its fun and watching your videos is so entertaining and helpful thanks!

• Woot!

Presenting math via video is tough because, unlike a teacher in the classroom, you don’t know (and can’t fix) the moment when your audience gets lost. Except for Nancy: I’m consistently impressed how she always anticipates where folks may have trouble, and does both careful repetition combined with insightful examples to always get even the most difficult concepts across. Also present when needed are careful pauses, to let things sink in a bit before rushing on. So very perceptive of her audience.

What helps make the math and pedagogical content work is Nancy’s presentation technique. First, her voice: A calm, unrushed and unaccented voice with very clear diction and enunciation. And, occasionally, a touch of irony, sarcasm, or just plain snarkiness to spice things up. Second is her clear handwriting and careful use of colors.

Finally, the editing: I especially like small details the whirring audio used during fast-forwarding through extended periods of writing (without commentary). Very well done.

• Damn her teeth look like she just came out of colgate comericial.

• You should do ASMR

• Wonderful to have you back. You have the best math tutorials on YouTube. Thank you for everything!

• Why the new channel though?

• Keep it up! I have always recommended you to all of the students that I tutor for supplementary help. You’re excellent!

• Hell yeah Nancy welcome back. Missed ya

• Why tho?

• I’m very glad you’re going to continue (:
I hope things have been well and you’ve had happy holidays. Thank you for your help.

• Hey ur sooo damn cute….can I jus get ur number personally…..?

• We are happy to see you too nancy

• thank you for helping me take better notes than my teacher could ever teach! now i am getting 105’s on all my tests 🙂

• ayayyayayayayay NANCY IS BACK!!!!!!!!!!!! finally, waited enough!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! <3<3<3<3<3<3<3 Your videos were amazing!!!!!!!!!!!!!!!!

• have numbers changed? has there been some radical new discovery that makes your old channel obsolete?

• Can you please do a review on the Algebra I Regents Common Core? Roughly 3/4 of my entire class is currently failing because our teacher cant explain to us a lot of the topics on it such graphing inequalities. More than half the kids who take this exam in New York fail it or get below a 70. I think you’d be helping me and thousands of other kids if you can review some of the topics on it. Thank you so much! Also your previous channel covered many topics that helped me pass my finals so thank you so much!

• Thank God you are back , your video helped me alot , what happen to your old channel ?

• Hi Nancy, Nice to see you back with new maths videos. The ocean of mathematics is full of amazing things and you make them more interesting and beautiful.

• Manoj you made my week, with this comment 💚

• Welcome back Nancy ❤️

• I love you .

• Yeah I’m going to subscribe. Pretty helpful. Just found a bunch of videos from your old channel about topics I needed to understand, convenient. Pleasantly surprised by the quality. I was greeted by a warm personality. Don’t know why but you seem nice, maybe from the way you explain things calmly. Kind an odd thing to pick up on when someone is explaining maths to you but oh well. I’m from belgium and a lot of dutch math videos are unclear. They explain it as if you have to follow their train of thought telepathically. That being sad, you explain it very clearly and seem to relate to and understand where people usually have trouble following. So good job an keep up the good work. And also, this might be kind of important, I would upload a video to your old channel announcing that you have a new channel. Very confusing and unclear, a lot of people seem to still be subscribed to your old channel absolutely oblivious to the existence of the new one. I really don’t read the description on most videos, I don’t think a lot of people do. Only reason I read the description that stated that there was a new channel was because I was actively looking for any sign that you announced the move. Just my feedback.

• Hey my love;)

• Awesome. But you should be on your old channel where everyone remembers you 🙁

• Nancy, so glad that you are back making new videos!

• LOL I watch you videos!

• Nancy… i’m not gonna lie. I’ve fallen in love with you XD

• Glad you’re back Nanci, wish you the best luck !

• Got hooked on mathbff, and will check out this new channel as well. Given the need to review some basics, however, is there a way to sort these presentations in order to achieve a logical progression?

• Gorgeous!!

• Why the new channel?

• I’d love videos on solids of revolution. Disk/washer and slice method..

• Nancy!! I just aced my test today thanks to you!!!! THANK YOU SO MUCH

• Wow, I just subscribed your other account yesterday and just found this! I’m glad your back and hopefully you can upload calculus 2 and 3. 🙂

• Thank you, Shana 💛Which calc 2 and 3 topics do you wish I had?

• NancyPi Well I haven’t got up to Calc 2 yet but you can do like application integration, infinite series.
Also, can you upload for related rates and optimization topics?

• I am also excited for your new videos

• Welcome back Nancy! ☺️

• Beauty and Intelligence – Nancy, you got it all !

• im taking a college calculus 1 class and im dying already and I’ve only had two classes..PLEASE MAKE BASICS OF CALCULUS VIDEOS AND LOTS OF VIDS ON CALCULUS THANK YOU YOU ARE AMAZING

• bruh

• Yassssss

• Hi Nancy! Can you please solve some topics on Differential Equations and Advanced Engineering Mathematics? You discuss it ever so smoothly. Thank you!

PS thank you so much for returning on YouTube. You’re gonna be a lot of help!

• thank you Harvey! 🙏 Which Advanced Engineering Mathematics topics?

• Thank u so much! So excited to have u back Nancy can’t wait to learn math from the best of the best

• Nancy, thank you for helping me pass my first semesters of math!!!

• Hey Nancy the great .. could u pls tell me where did you learn motage/video editing?

• Woop woop! You’re an absolute gem. Thank you sooo very much for all of your help ^_^

• Nancy can you show me how to do linear equations i didint care about math but i want to learn how i cry bc i dont get it

• THE LEGEND

• Nice work! You made THE BEST videos with excellent explanations. Please continue to make the World a NICER place! Thank YOU so much!

• Nancy really obliged with the way you explain things. Hope you go higher!

• Im here for the math

• bae is back !! 🙂

• Very glad you are doing videos again. Your explanations are very simple and clear with solid examples. Better than many textbooks

• Thanks for all the time you put into teaching math. I hope this new channel is even more successful than mathbff

• Maybe you all know, but what happened to the old channel?

• Nancypi binomial woman of mystery!

• Your differentiation explanations on your former channel helped me so much! Can’t wait for new vids here 🙂 sending nothing but love to you 🙂

• do videos on algebra 2 fuck all the rest I need to pass math

• WELCOME BACK!!!! Can you do some more Trig videos?

• My Queen !

• Nancy, have you looked at Sidefx.com Houdini for visualizing your math. It’s free. It’s the best math software out there. Great to have you doing more videos.

• Will you do a video on the fundamental theorem of calculus?

• Thank you! I am so inspired to make own videos for my students, in Swedish. I know that we learn in different ways, I also work as a teacher for students with special needs, and I learn the best when I can see the teachers face mimic and body language. Please go on doing what you do!

• Yeayyy nancy is back…. Thanks for coming back…

• Im gonna go back to school again

• All my old videos will be moving here to NancyPi soon!!  <3 <3

• When will you be posting your old videos and new videos to this account? It has been a month!

• Do matrices

• Teach vectors please nancy ☺️

• Great job Nancy. Keep putting those videos up. It helps me to show my young daughters that one can be beautiful and still love math.

• @San Samman so Was tgere any Previous channel of her?

• I just cried! Nancy you helped me with my math and when I haven’t seen you post anything it broke me. Your the only person that really helped me understand the material when my professor’s couldn’t. Don’t ever leave us again!!!

• You helped a lot with math in college for my econ degree.

• Am I the only one who is suddenly really excited to learn math?

• I’M SO HAPPY YOU’RE BACK!! You have NO idea how many times you’ve saved my butt from failing. You’re a blessing!

• Thank you! Looking forward to Calculus help. The lecture doesn’t cut it. Oh, and reading the book. Good luck with that!

• Hey Nancy, love your videos. May I ask, why the channel change — why start your subscriber counter again from zero? Seems unnecessary unless you’ve lost access to the google account, or there’s a saboteur withholding access. Everything ok?

• The legends are true. She has returned.

• Hey babe I missed you, please don’t ever leave me like that again 😘 p.s I’ll pick up the kids from school tomorrow. Love you, bye <333

• So she still doesn’t have a ring on her finger. So I’m not mathematically eliminated from dating her yet. Cool.

• nice!!!

• Thank you for coming back and I was just wondering if whenever u have the time if u could do a video on solving quadratic equations using imaginary numbers

• Honestly Nancy, I have watched so many of your videos…you have really been a huge help to me in getting through Calculus…I really appreciate the work you do, and so glad you are back with a new channel and will be doing new videos!!

• Glad you’re back. I need a break from Sal.

• Why abandon your channel with 400k subscribers?

• Looking forward to the new videos. Subscribed so I’ll be notified!

• Can you please do a video on optimisation methods for rates of change?! Thanks love your videos!! xx

• Yea!! Great to see you again.

• These vids have single-handedly gotten me through college.

• GOD BLESS UR BACK

• Hiii Corona virus

• Hope you will post every week, God bless you

• im glad that you are back <3 i love you baby

• I think will be nice if you use facebook as well

• Thanks your videos help me a lot.

• Why a new channel?

• Thank you Nancy, you are the best!

• may your calculus videos be as populated as the limit of e^x from the left

• NancyPi, how do you manage to write on your videos? Our whole calculus class has been watching your videos and have always been crafting theories on whether you write with a mirror or backwards.

• Why new channel?

• Ahhh! You’re back!

• Can we get an algebra matrix video in the future?

• why dont u go back to mathbff u have 100k subscriber there n millions of view

• you helped me alot!

• thank you

• You rock! Thanks for the tutorials.

• Love your videos, they help so much! And, they are right to the point when you don’t have a lot of time!

• Nancy 2.0 yeeeeeessssssss!

• I’m an engineering student and I need help with Limits… 🙁

• Why do you have a new channel?

• Why did you have to put these videos on a new channel. Mathbff was fine to me. I must be missing something.

• thats hawt

• Why do you have a new channel? Also was it a clusterfuck getting back here XD

• hahaha it really was 😉

• NancyPi Hey, don’t wink no one likes a tease XD 😉

• hi nancy, your videos were amazing, it helps me a lot on my studies. can you teach how to compute the probability of an event to happen too???

• Nancy !!!!!!!!

• ur videos r so helpful they helped me a lot

• yay so excited to see ur videos i really learned a lot from u thank u soooo much keep going❤

• Welcome back Nancy !!
Your math explanations are concise and to the point.

Thank you a tonne !!

• Thank you Nancy for doing these videos. You do a great job explaining difficult math problems which has helped me so much. Just wanted to say thanks.

• So excited that you’re back. You and PatJMT are my Dream Team.

• lets do this ! u helped me get my associates degree but I got sent back to advanced algebra after college courses didn’t meet criteria when I switched to UW Milwaukee can’t wait to fine tune once more

• You’re back! Multi-variable calculus and differential equations, please.

• Which multi-variable calc topics?

• My professor said she’ll start partial derivatives next class and move on to integration in about two weeks.

• Would wife up ReAl QuiCK

• No new videos?

• Nancy is comming…..

• You never age.

• Do Integration by partial fractions video! The other channel doesn’t have anything on it.

• You still look the same after years

• I missed you Nancy!
I thought maybe you got recruited by Elon Musk to calculate interplanetary trajectories for SpaceX. LOL
Great to see you though!
I activated the alert bell to get all of your future videos.

• Make a vlog channel too

• 😳 crushing

• Last year of high school for me, LETS GO!!

• Hi Nancy, any new videos lately?

• Holy shit this is so awesome!

• Why did you give up your old channel though? Did you sell it to someone or what? You had like 400,000 subscribers. Why start over?

• Why did you decided to move channels? I mean the other one already had a strong network and subscribers, just curious!

• just started stats classes. do you have stats lessons and do you use R studio in any videos ???

• You are more brainy than our maths teacher (and definitely more pretty) 🙂

• thx to come back! can u upload all of ur old videos over here? 😀

• ♥️♥️♥️♥️✊🏽😜 thank you sooo much Nancy your the best math teacher ever

• Oh man

This should be an interesting comment section.

• Love your videos. If I may give one suggestion for future videos.. could you please at the beginning of your videos, give a brief example of a real life application for a given theorem? In eg. ‘ Logarithms are this and they can be very useful when trying ro figure out that’

• what happens when the denominator is not a quadratic equation, will i still set it to zero? I hope to hear from you soon. thank you for the videos, they are really helpful, briefly explained and easier than i thought. keep it up the good work of sharing the knowledge you have with others

• Way better then person’s my math lab video. Thanks for using different colors ink when solving problems.

• Whatever you do, it works. Whenever I’m doing a math test these days, I have your voice in my head explaining what to do. So thank you, Nancy. I hope you enjoy what you do, because you do a lot of good for a lot of people.

• nyc dp yr 😉😉

• you are the best i love your channel.

• IM EVEN MORE HAPPY TO SEE YOU ….I NEED HELP WITH RIEMANN SUM !!! THANK YOU AND WELCOME BACK !!!

• Nancy, I love your videos.  I am taking college algebra online.  The course is difficult since I do not have an instructor.  Guess what, I found one and her name is Nancy.  I love the way you explain the math problems.  You give the reason why something can or cannot be!  Thank you so much.  You have helped me so much already.  I know it takes time to create these videos, but from one avid fan!  I appreciate you!!!!!

• Why the move?

• thanks nancy really looking forward for some videos, specially trig ones

• thanks miss Nancy for coming back thanks alot

• ur so sexy

• I MISSED YOU!!

• Every college students savior has returned, she will help us slay the math dragon!!!

• You Rock!

• i wonder why mathbff removed (?) her she so gooood tho

• This is a family event for us and I really appreciate sharing your knowledge … Thank you.

• Awesome! I needed some help on some equations for the math portion to get my teaching credential (along w/other items). Also, I appreciate you taking the time to make sure the lighting, sound and your studio setup were just on point. Thanks so much and continued success! —Steve

• Every time I watch one of Nancy’s videos, Elton John’s “Someone Saved My Life Tonight.”

• Yay I’m so glad you’re back Nancy! ❤

• A lot of helpful videos that go a long way helping me on my math journey. Thanks for your work.

• Can you cover linear algebra topics? Possibly multi variable calculus as well?

• So glad you’re back. Pretty much the best maths videos out there. (from a grateful student in England).

• I fell in love with math now.

Even though I am finish with math

• Nancy, may I ask why you had to start a new channel?

• We love you. Please don’t ever stop teaching..

• Thank you for sharing your knowledge. It has helped me greatly!

• You’re amazing.

• Silly question: But, what should an 8th grader do in order to get started with Calculus on Khan Academy? Asked another way, what are the pre-requisites for an 8th grader, for them to get into Calculus via Khan Academy? Many thanks in advance!

• Is this just for students? I’m older (60 years old) and I am interested in relearning what I used to know as a student. Is this a good channel for my needs? Are there special channels for older people wishing to brush up on their education?

• How did u get into mit?plz tell

• Jesus Christ you guys are rude

• Hi Nancy, I am Engr. Towhid.Can I get your mail address NANCY to communicate with you

• you know solving concrete mathematics?

• Loveyou❤

• Missed you. Welcome back

• OMG Nancy!😱😱 I am ecstatic to see your channel. I have been searching to see if you have a new channel and I couldn’t believe my eyes this morning when I goggled mathbff and saw your new channel. I am trying to pass my Pre-calcus, hope there will be some videos on those subjects. Thank you!🤗🤗🤗

• didn’t she sound a lil sarcastic!! ◔̯◔

• I can move on with my life now. 👍

• I am so excited! Thank you so much Nancy!

• Hey, lady! I just wanted to give you a shoutout. I’m taking a calc class after 8 or 9 years of no math whatsoever, so thanks so much for the help! Keep doing what you’re doing. You’re a good teacher.

• For real though. I took a pretest for the midterm and got ~40 or so. I got a 98 on the midterm last week.

• Hey Nancy, Glad you’re doing vids again. There were no computers when I was in high school,( Yep, I’m old). Because of you, I was able to help my grandchildren with their math homework. One is graduating high school this year and the other is in the 7th grade. Both make A’s and B’s in math. Now I’m helping my Son-in-law who is getting a degree in robotics. Thank You for helping me, help them.

• oh

• Please do more integral problems and basically Calculus 2-3 material. abs max and min with constraints, local max and min 3 dimensions, vectors, integrals trig substitution and integration by parts with trig functions please.

• Hi Nancy. I posted my thoughts to you about a month or so ago, when I first saw you. You are so brilliant, and so beautiful. I am so glad you are back. Nonetheless, I am a land surveyor in line for my Land Surveyor Intern exam. I was wondering in that light, would you be able to provide a video(s) on intro Algebra, specifically on how to add, subtract, multiply and divide fractions? Or, a comprehensive look into the mathematics of land surveying. I have found if I don’t know fractions, and how to work them, how will I know how to work through trig, you know. I need help getting just the basics down. Can you help? Sparky…..

• I missed u so much..I was sad when I didn’t saw u on math bff….but when I got u in your new channel…I’m very happy….I love ur teaching style….thank you…

• cute

• Welcome back 😀
can’t wait for more videos

• I love you

• Welcome back…

• wow!!!! you are back

• Yay! You’re back! Please do some differential equations

• Engaging and distracting at the same time. Smh.

• It took me way too long to realize you made another channel ! The link popped up on one of your videos. Super happy you’re still around.

• Merde, now I have to unsubscribe the other and re-subscribe to thisXD

• We Love You! Put ads on your videos! I want to support you that way. Maybe even patrion!

• Add videos related to linear algebra and abstract algebra.

• I’m also happy you are back

• Ohhh she is sooo hottt

• My daughter who is a C/Sgt in Civil Air Patrol, a pilot in training, and just a great kid loves your videos and also loves Danica Keller’s books. Nice to have someone to identify with I suspect. Keep up the good work.

• So glad to have you back!

• can you make a video on integration with volumes and shapes and the sort?

• OMG FINALLY Thank you! You’re videos are so awesome. They helped the most back in the day

• can’t find your videos of integral !!! please we need you

• Just finished my math exam in grad.

• It was terrible.

• This is what is wrong with the world and will never go away. Someone who UNDERSTANDS advanced math and is willing to educate us is played by others for monetary gain and the net result is we live a ” goodfellas” life.

• You have been very helpful! Have you considered doing an entire course on, say, calculus. As opposed to specific topic videos? Just a thought.

• You’re amazing😭❤

• Wow perfect timing for me! I just started taking calculus 1 and I stumbled across youd chain rule video, it has been so helpful! I take color coded notes kinda how you were teaching. I’m glad you’ll be making more videos!

• Could you make a video explaining how to find; Marginal cos, Marginal Revenue and Marginal Profit

• Yay! I love your explanations… I used them several times in my Algebra II class last year. Glad to have you back!

• Nancy Glad you’r back 🙂

• Could you show us how to solve a quadratic formula? I have an equation of 3x^2+13x=30. Thanks!

• Hi :). I’m a big fan of watching and making math videos. I will definitely be checking out your videos. I teach third grade but I love learning new things for myself. I also have a student who is extremely high in mathematics. I want to push him so I may be able to use some of your content. If you ever want to make a math collab video let me know. I’d love to do something with you 🙂

• Love to see u back 🙂 💖

• plz upload 10th class match lectures…. i m waiting for your lectutres mam…

• I have shared your instructions with my students for quite some time. I like the approach you use and your thoroughness. I am retired after 40+ years but tutor weekly. Thanks again!

• no study no english but wathing u

• nancy i am habtamu from ethiopia i want to say thank you for your video

• it is easy to understand math by watching your videos thanks alot

• 선생님 앞으로 영상 많이 만들어 주세요!

• Nancy! Where are you? From Chicago

• You are a great math teacher Nancy! Love your videos!
Nice new, classy hair style!

• Excellent videos, great initiative. Congratulations

• Nancy, please upload videos on differential equations and Laplace transforms. Thank you.

• Your teaching experience is phenomenal! You are just the best. Went from “i hate math to wow, it’s this easy” You are the greatest. Thank you.

• omg you helped me get through calc years ago

• Your cuteness reason of my killness

• I

• you are extremely helpful .. and now i can solve maths with more interest … 😍😍 and u r gorgeous too

• Yo nance, u gotten me outta a hole many time thanks for that. Keep that content coming girl, and make some dynamic programming (operation research) and statistic video for ya boi. Time is of the essence but patiently waiting.

• I love you !

• Planning on doing English classes. Mind letting me know what camera you use?

• AAAAAA I CAN’T EVEN EXPRESS HOW HAPPY I AM THAT YOU’RE BACK! I’m in sixth form right now (UK equivalent to high school I guess) and I’ve been basically relying on your videos to help me get through my first year of Maths and I loved every video and the way you explain and just wished there was more because you can make anything interesting and you’re just such an angel and aaaaaaa thank you for being back I’m looking forward to your new content!!
And here, big group hug!

• why was she gone?

• Hello! Can you do a video on improper integrals? Thanks! ~Luis

• Dear Nancy
Love your videos which actually help me understand what is going on rather than just doing it parrot fashion. Regarding weirder logs, you mentioned natural logarithms but how about a video on Napierian logarithms?
You might wish to mention Napier’s Bones in passing
or

Lastly, fascinated by the writing back to front? A video trick or do you do mirror writing 🙂
Thanks again
George

• i cant focus , how i can learn when all time im blushing hearing and seeing u teaching

• Very good to see you back! Are you single?

• Nacy! You make my math life easier! Lol.

• Hi Nancy…how are you???

• I love your. Channel. I am glad you are still here.

• Thank you too Nancy. Keep your videos coming; they are good, simple & lucid. Best of luck dear.

• love you channel, i wonder if you can teach vectors, its really foreign territory to me, thanks

• Hi! Just wondering though. Why did you create a new youtube channel?

• YYYAAAAAAAYYYYYYYYY!!!!!!!#

• Can you help me with the QAnon Clock?

• How can anyone learn anything from from you;everytime i watch your videos and half the time i spend watching you?
You should wear a hijab so that people don’t get distracted

• Why start over? ….you had close to .5m subscribers on your last channel, at least you would be getting some kind of compensation for all the time you put into these videos.

• Good to c u too
.

• please Nancy…we do mathematicS…not mathematic….math? :-/

• Very nice channel!!
Why don’t you teach us higher mathematical concepts in your way ??
Like Laplace transforms and differtial equestions #mathbff

• Yeah… So.. when are we getting married? 😂🙃

• i am willing to marry math with you by my side

• Happy your back….. subscribed and liked.

• Yaaay!

• I searched for you so hard!

It’s about: “How to Remember the Unit Circle” and “Derivatives… What?”.
Thanks!

• Do you have a website? are you tutoring also?

• Finally found u… Thank God…

• Hey Nancy, I have to say that your video on calculus are really helping me and also using khan academy. Do you think that you could talk about finding the derivative in table charts

• what was your old channel

• Please post more!! You explain everything so well!! 😊😃

• I searched you again on math buff but …..I found you here at last …..Very happy to find you.

• welcome Back…!!!

• My name is Glenn Perhaps. You are a great mathematician . I have a theory concerning faster than light speed, I understand the concept of faster than light, but I need a better understanding of a more advanced math, it’s hard to discover. Your trig helps, but I need a more advanced versions. Moving on, I know the secret of you writing backward. You write with both hand. You prefer writing with your left hand because of the clear board in front of you. In front of you is a clear glass board. Therefore, you are writing from right to left.

• She is back!!! Time to enroll in another math class.

• Damn I think if all women as nice as you we would be in trouble . Keep up the good work.

• No wander that song is about am in love with a teacher.. they probably meant it for Nancy.

• It’s really great how you explain the math, I used to hate math growing up in school, but as an adult now I really like it, thank you for making it easier for me to like math even more!

• I think you do an excellent job with your instruction videos.
Are you a teacher, or are you just doing it for fun?

• Hi Nancy,
Welcome back. I’ve to say you make math so easy like drinking a glass of water. You’re & will be the best teacher in math.

• Nancy, you asked for some ideas. You should connect this channel to your FB page, that way FB could direct traffic to Youtube. Sounds a lot like the chain formula..lol, Calculus !!!

• Your candle will go out long before your legend ever will

• you re so so pretty!!! from japan

• Hey Nancy, there is 1 dead give-away in some of your videos that shows how you write backwards. I would be happy to share my observation with you in a private email. But I do have to say kudos to you for pulling this off 🙂

• Can you please make a video looking at how different fractions involving variables are turned into exponents? No one taught me this and it’s making calculus very difficult.

• Με αφορμή την εναλλαγή λογαριασμών στο YouTube κερνάω ποτό

• She Still Around Doing Math Videos, Well I Graduated After Flunking Pre-Calc Twice. I’m Going Back, Cause I Got Years Of Practice Now.

• I love you

• MathBFF could have been mistaken as mathBoyFemaleFemale…

Thank YOU!!!

• Can you do some partial derivative vids? maybe throw in there how to deal with constants in general and how to deal with them in the numerator and denominator. I’m having a hard time knowing when to 0 and when to use the quotient rule. Thanks for your time and effort.

• You are looking so pretty. 😘😘😘😘

• Te amo

• Teach us Euler’s , Fourier series transform and inverse Fourier and z transform and so on plz

• where’s the old channel?

• I can’t stop looking at her face. She’s gorgeous!

• I thought you’d deleted your old videos and was annoyed because you had a good video on trig / cosine and sines etc. Lucky me I found them.

• I really wished you did some physics videos too. You’ve really helped me with math.

• Can you post implicit derivatives please,
You the best ever 👍👍👍👍👍👍

• you remind me of Christy Carlson Romano. sorry that is completely random but hey, I love your channel and you are the reason I have nearly made it through my engineering degree. please keep making videos!

• Thank you very much for your inspiration and motivation!
Although, I never liked math until grade 12, and although most of what you explain to the geniuses out here , just flies over my head! Nonetheless, some how it’s so insightful and enlightening.☺️

• I learned too many things from your videos keep going you are great at explaining mathematics

• Where were you when I was in school?! My math teachers sucked!!

• Hi Nancy, are you still making videos? Could use a proof of Pascal’s rule.

• You looks hot Nancy …wow your brain full of math..

• Hai Nancy, can u share how to make video light board like you did

• I love you

• hello nancyPI from South Africa

• Thank you very very kindly for all your help, I need all the help I can get with calculus, struggling with calculus
