we wonder how some guys or even one of your friend when calculating while on doing maths sums or even if you visit a groocery shop ,its their ability knowing or unknowingly they do.

I am the one who find difficult in math ,and i found this simple maths calculating tips when i just goin thru SU,

How it Works?

Let me show you, if you want to get square of 104 ,what will you do?

putting 104x104 then multiplying each consecutive term? Is that fast. .
Here we go, you first decide whether the number you want to square is more than 100 or less than 100, if its more than 100 means it is very easy way to calculate 104 X 104 with in few seconds.
104+4 = 108 and show 4X4 = 16 together with 108 ,
and the answer is = 10816 .

Like that, if 112 X 112 = ? 112+12 = 124 and 12 X 12 = 144 now we add 1 left side of 144 in 4 of right side of 124 and answer = 12544,(ie,we added 3rd digit of 124 with very first digit of 144).

But ,if 96 X 96 = ? How to calculate it,as its less than 100.It is very simple 100-96= 4 now 96 X 96 = ?
96- 4 = 92 and 4 X 4 = 16 = 9216 is the answer.
