Fast Math Trick
- Indian people...
are the best at teaching math and economics. Many of my professors are Indian. They can teach pretty well, but sometimes they are hard to understand....lol

(104 times 4) =
(100 times 4) = 400
(4 times 4) = 16
Similar concept as the video. Divide and conquer. Your approach applies to more general cases though. It will work with any multiplication.6788594 - 1

(a b)^2 = a^2 2*a*b b^2
always;)
as simple as that5694879 - 1
- little correction
is ( a + b )^2 = (a)^2 + 2ab + (b)^2
By evan520_520 1188401274 Reply Spam [-1] Moderate Up Moderate Down Remove
therefore (104)^2 = (100 + 4) ^2
= (100)^2 + 2(100)(4) + (4)^2
= 10000 + 800 +16
= 108164679533 - 2
- (a+b)² = (a)² + 2ab + (b²) is better...
Your formula is better,
By Muuip 1188401768 Reply Spam [+0] Moderate Up Moderate Down Remove
the one on the video is great for mental calculations but only for numbers around 100.
Yours is good for all numbers, althought for numbers around 100 the formula from the video might be easier for a few people to work it out mentally.
Thanks for the formula, keep them coming!

I suck in other matters, just focus on your own talents and make something great out of it.
By the way, by failing Algebra you actually learned something about math, keep learning. :)4005265 - 5
You are a REALLY good teacher pal. I'm learning a great level of math from you. I would defintely love to watch more of your videos. :) Also, I'm 18 and am so, not meant to be interested in maths. Lol.

a= 100, b=0, c=4 a^2 c(2a c)
(a b c)^2 = (a b c)(a b c)
a^2 2ab 2ac b^2 2bc c^2 (general cross-wise method) b=0 so
b(b 2a 2c) c(2a c) c^2=a^2 c(2a c),
test it out
4(200 4) 10000 = 816 10000 = 10816
