You are a gifted man sharing his gift with others. You deserve way more subscribers man. You're not just any guy sitting there creating the ten millionth video on youtube on how to multiply fractions, you take what you know, and teach them in bite sized lessons full of dense but easily digestible information. I clicked on your "How to calculate faster than a calculator - Mental Maths #1" video and I'm like let's just give it a try, but I'm so glad I clicked it because what you taught was soooooo on point nothing complicated or anything. 75 x 75 = 5625 23 x 11 = 253 42 x 48 = 2016 Like this is too good to be true, yet every time I check my answer on a calculator the answer is spot on. I've been doing math since Kindergarten and just did a quadratic equations test today in my Pre-Calculus 20 class (grade 11 pre-calc) but in 5 minutes I learned how to multiply 3 types of 2 digit by 2 digit multiplication problems in my head no paper needed or anything so thank you. What I'm saying is you stand out as a great person and I hope your fame grows man I know I'm going to be watching your videos more often now. Like really though you're videos are so short but straight to the point and they teach so much in so little. You should considering writing a book about your little tips and tricks, if you can cover so much so fast in 5 minute videos, imagine how much you could cover in a whole book with all your tips and tricks. You're awesome man. Also what did you study in university?
Sir ... I have an small request... For kids u can do more mathematics trics ... Like +,-,*,/.. I think it's very helpful to them... Please make a more videos for kids.. for below 5th standard...in videos if u r giving more mathematics tricks for them , they can learn maths very easily...if u r comfortable Please post some simple maths tricks to kids.. tq sir
Differentiation is like "instantaneous rate of change". Integration is "area under the curve". And remember both are kind of "opposite of each other", or reverse process of each other. These terms sound tough when "domain (x, horizontal axis) is continuous". But if domain is discrete (like only integers allowed), then, Differentiation is simply difference: "next value (of function at a point) minus present value (of function at present point)". Mathematically, y'[x] = y[x+1] - y[x] or also y'[x] = ( y[x+1] - y[x] ) ÷ 1 (Why "1"? Because smallest step size is 1 when only integers are allowed) Example f(x) = { 1 , 1 , 1 , 1 , 1 , ... } f'(x) = { 0 , 0 , 0 , 0 , ... } [Derivative of constant "1" is "0" see?] (Now, for continuous domain, i.e. "x is continuous", we replace "1" with "h" which is extremely small number, i.e. limiting value "h approaches 0", and you get definition of derivative) y'(x) = lim(h->0) [ y(x+h) - y(x) ] ÷ h This is actually slope, slope = rise ÷ run rise = y(x+h) - y(x) run = (x+h) - x = h Similar to, slope (m) m = (y2-y1)÷(x2-x1) Then just see proofs memorize the derivatives of standard functions and their rules (addition or subtraction, product rule, quotient rule, chain rule) & do homework. Now Integration in discrete domain: Integration is simply sum: "Sum of all past values till present". y[n] = ... + y'[n-2] + y'[n-1] + y'[n] or also f(x) = SIGMA( f'(x) dx) Example f'(x) = { 1 , 1 , 1 , 1 , 1 } f(x) = { 1 , 2 , 3 , 4 , 5 } [Integral of constant "1" is straight line (1,2,3,4,5,...) see?] Like above, 1 is added 5 times. 1×5 = 5. In continuous domain it's like area, (height=1) × (width=5) = (area = 5) In continuous domain, width is just very very small (dx , limiting value , x approaches 0) and height is function (to be integrated). Integral is kinda hard compared to differentiation. Just recall differentiation results and adjust your function in those forms and just write integral.
pls can u help us to find the fith root of 3 digit and i really liked what someone said that you should try to make small trick to kids under 15 i really like what she said or he. well as i was saying then pls help us to find the cube fouth fith of of 222x222x222, 222x222x222 cube fouth and fith of this number u have only showed us the square of 33, 64 e.t.c but u have not showed us how to find 3 digit on square of eg suare of 231 square 421 square i know am asking fo a hard thing but i really enjoying your mental maths. 2. pls try to make a video for little children maybe some trick for maths so that u can catch them young, when they grow up they will not find it hard fo calculating maths thanks you this is what i have to say
Merci, j’aurais voulu parler avec vous de ce voyage jusqu’à elle… nous nous sommes laissées apaisées. Je lui ai dit… je suis sortie de là avec le sourire… est-ce que de vouloir retourner la voir signifie qu’il y a encore des vides à combler ?
@@mathOgenius ok sir i will try again. sir pls can u teach us how to find the cube of 23, 54 without using a calculator i know it will take you time from trying it but please take your time before you upload the video and again can u also show us how to find 3 digit on fifth root and also show us how to do fouth of a number thanks
I hope you enjoyed ! Thanks for watching!
No thank u ;)

Thanks for your kind and encouraging works , I am currently doing a Phd in Astronomy and Astronomy (1st year )
Great trick...have been following your channel since a while..great work..
Thank you once again 💕. Can you please tell us how to remember the percentage and fraction values of a number
Thanks for your efforts.Nice videos😊
I have learnt too many tricks and concepts because of you.
Thank you so much bro 😇😇
844596301-last 3 digits are 301. 30 divided by 5=6 thus 61. Numbers ending in other numbers (2-9) rely on different yet similar easy equations.
pls can u upload another video, i can not wait for another tricks.
thank you for spending your time teaching maths
Thanks For Sharing!
Sir can say some tricks for solving square roots and cube roots
what should i do
Thanks so much. You are an excellent teacher. Luv your videos, plus you look just like my son!! lol God bless you
Thanks for sharing this trick!

Lovely class
It really helped 🎀❤
Can you do for ANY number?
Nice and thanks.
Thanks sir
Thanks bro
Sir pls explain the meaning of differentiation and integration in details I didn't understand that's why
Differentiation is like "instantaneous rate of change".
Integration is "area under the curve".
And remember both are kind of "opposite of each other", or reverse process of each other.
These terms sound tough when "domain (x, horizontal axis) is continuous".
But if domain is discrete (like only integers allowed), then,
Differentiation is simply difference:
"next value (of function at a point) minus present value (of function at present point)".
Mathematically,
y'[x] = y[x+1] - y[x]
or also
y'[x] = ( y[x+1] - y[x] ) ÷ 1
(Why "1"? Because smallest step size is 1 when only integers are allowed)
Example
f(x) = { 1 , 1 , 1 , 1 , 1 , ... }
f'(x) = { 0 , 0 , 0 , 0 , ... }
[Derivative of constant "1" is "0" see?]
(Now, for continuous domain, i.e. "x is continuous", we replace "1" with "h" which is extremely small number, i.e. limiting value "h approaches 0", and you get definition of derivative)
y'(x) = lim(h->0) [ y(x+h) - y(x) ] ÷ h
This is actually slope,
slope = rise ÷ run
rise = y(x+h) - y(x)
run = (x+h) - x = h
Similar to, slope (m)
m = (y2-y1)÷(x2-x1)
Then just see proofs memorize the derivatives of standard functions and their rules (addition or subtraction, product rule, quotient rule, chain rule) & do homework.
Now Integration in discrete domain:
Integration is simply sum:
"Sum of all past values till present".
y[n] = ... + y'[n-2] + y'[n-1] + y'[n]
or also
f(x) = SIGMA( f'(x) dx)
Example
f'(x) = { 1 , 1 , 1 , 1 , 1 }
f(x) = { 1 , 2 , 3 , 4 , 5 }
[Integral of constant "1" is straight line (1,2,3,4,5,...) see?]
Like above, 1 is added 5 times.
1×5 = 5. In continuous domain it's like area,
(height=1) × (width=5) = (area = 5)
In continuous domain, width is just very very small (dx , limiting value , x approaches 0) and height is function (to be integrated).
Integral is kinda hard compared to differentiation. Just recall differentiation results and adjust your function in those forms and just write integral.

I need help with this question.
Given that 245 × n =m,find the smallest value of n such that m is a perfect square.
1/5
1/5 is the answer
Great job

There is another Top secret way WITHOUT memorization
Tell me pls
I don’t really understand how he did come to the first starting digit like the 73 and 58 how he got the digits 5 and then 7 for the second example
