I've always wanted to do number manipulations in my head. I am no savant, so the best I was able to get to was powering up any 2-digit numbers within my head in less than 20 seconds. It's a very simple trick where you multiply the nearest whole number with the equi-distant number from the number you are actually squaring and adding the power of the distance. For example, if you want 99^2, you do (99+1)*(99-1) + 1^2.

I came across this on Google Video and I find this man to be simply amazing...
