it really works !!










How does it work??!!

For every 2 digit number, subtracting the sum of the two digits from the number, would give a number that is a multiple of 9.

Don't believe?
Take 88 for example
8 + 8 = 16
88 - 16 = 72!

Still not convinced?
Take 64 for example
6+4 = 10
64-10 = 54!

Amusing.. ain't it?

PS: Look carefully at the pictures-- all the pictures for multiples of 9 are the same!!
