Vedic Maths

I was just sneaking thru the web and i got really good stuff about are acient mathematics. though using their rules everyting seems magical but there is a proof behind everything.ex.

Lets multiply 107 with 104 using normal way will surely take more time then the way i am gonna tell u

1 0 7 ( 7 more than 100)
x 1 0 4 (4 more than 100)
======
(1 0 7 + 4 ) ( 4 x7)
( 111) (28)

So Answer : 11128

so instead of multilying three digit stuff, the problem filter down to multiplying just one digit numbers and simple addition.But keep in mind the base 100!!. here is one more example

1 0 9 (+9)
0 9 6 (-4)
=========
(109 - 4) (9x-4)
105 (-36)
104 (64)
=============
Answer : 10464

Will keep updating this blog with proofs and more stuff!!!
