Man,,,I’m glad this popped up on my timeline I miss math, I was a huge math nerd in high school and college. Thanks for reminding me of how fun math is !
Please teach mehh,I'm a loser in math..
stop lying brev
BAH! It was fun when ja was in high school and college. Im back in college for power engineering 3rd class. Alrdy got my 4th class. AND ITS ALL F#%*in math. We did complex quad equations in the first exam with FRACTIONS. I HATE FRACTIONS! Lol. I love math but we moved so fast and had no
Info :(. Or less. It was also a mix of calculus but at a much extreme level
The signature of a great teacher is making that which seems difficult easy to understand. That makes maths and numbers fun and enjoyable, confidence builders. Good show thanks.
Nostalgic.... It reminds me of my high school life ❤❤❤
dont stop uploading or i unsub
U ARE A MATH LEGEND WHO POSTS FROM PAST 12 YEARS AND HAS NEVER QUIT
Nice video to remember what I learnt like 25-30 years ago and probably forgot 15+ years ago. I often wish there was a quick way to recall all the math I used to know. Only remember the very basic stuff. Not that this is anything advanced either. But I basically just remember how to add, subtract, multiply and divide. And some simple trigonometry, sad.
Thank you for the refresher course in solving quadratic equations. 🤗💚
Thank you!
I am learning Math from you right now and literally you are the best teacher in this universe that I ever had on UA-cam💕👍❤️

Every video I watch with you I wish my high school teacher’s and college teachers would have broke it down so easily you are a gift to your profession. Darnell from landover
THANK YOU😭 been trying to figure out what I've been doing wrong for hours now
I really recommend this channel for learning :)
I literally just learnt quadratics yesterday I could’ve saved so much time T~T
Cross method bad just use calculator formula 01
Quad eq solves for all
I just learned it yesterday too
Lol
Found this channel since I was in 4th Grade (which was the year 2013); now i’m in the 12th grade, still watching these videos of yours. Thanks so much!
This method was really helpful! Should aid me in my exam. In a recent video, you said we can ask you to say anything in your 'nassaly thor voice' so can you say, 'Koala's should reign supreme on earth from ChattierTooth.' Asking for a friend.
You make it look so simple - 45 years after high school I finally get it :-(
Huh
huh
Thanks alot sir... You are best teacher I ever had.... Cause your way of explaining toooo much easier than had ever..... 😇😇😇😇
Sir I have a doubt
In one of ur previous video u discussed a beautiful method of multiplication using Vedic maths
But sir how to solve it if we get 2 digit number as carry as in the case of multiplication of ( 69 × 96 )
The video title was " How to multiply any numbers the fast way - Fast Math Trick "
Thank you very much.
I just found this on my recommendations and I actually learned it. O.o
Amazing & excellent way of explaining sir..... 👍👍
謝謝你的幫助，太棒了
good one - we're getting closer and closer to Trig and Calculus - hopefully
Thank you
Could you write the first one as x=1 and x=2 as well?
No
THANK U SO MUCH ILY ❤❤❤❤❤❤
I love tecmath
What is it use for or to solve what kind of problem ?
thanks
So, in the last problem where the result is 4+-√11, I got on calculator that;
4+√11=7,31(appr.)
4-√11=0,8 (appr)
Before that I got my results for plus=7,13 and for minus=0,6.
I think I wasn't that far though. I approximated some of the things I calculated too. Good for me since I didn't start doing quadratic formulas in school yet.
How did you get the 2
That was owasome but what if under the squerroud miness I mean negative what to do
eventually imaginary numbers must be used - (yes, there are imaginary numbers in mathematics)
Mais c est super simple en fait ! J' adore merci from France 🙋👍.
Can you make a video on how to solve cubic equations using the cubic formula next
b^(2) - 4ac = 1
X2-8x+5=0
Please explain how you got 11in the square
Yeah I don't get it
b^(2) - 4ac = 44
b^(2) - 4ac = 196
Silly me, my math isnt what it use to be. My answer was, Cheeseburger.
This problem you could do with the formulae
3x^(2) - 10x - 8 = 0
x = (10 + sqrt (196)) ÷ 6
x = 24 ÷ 6
x = 4
Can any of you tell me when did you learn it in school ? I'm mean which grade ? If you want of course .
i’m 14 ending yr10 by British system,we were thought those equations at the 9 grade/begging of 10 grade
I’m never gonna understand why so hard ?! Explain easy with our using these methods
I cant use this when the constants are so big
When do we get a face reveal?
Erm, I've just woken-up, this is a head-f**k for me, I'll just have a Coffee and come back later. 😔
Is it normal to learn that at grade 8?!??! They are teaching us that in grade 8 smh 🤦♂️
Lets say 0=3x^2-10x-8 what is a,b,c becuase this 0 is on the other side rather than the examples you showed us.
X=4
3(16)-40-8=0
48-40-8=0
3X^2--10X--8==0
3X^2----5X--4==0
3X=8+4=12/3=4
X=4
