1. ## Babylonian Mathematics

Can anyone explain how to solve base 60 problems.

All I know is my sister came home and asked. here's what she gave me.

a*b=[(ab)(ab)]/4-[(a-b)(a-b)]/4

Anyone make any sense out of it.

2. anyone?

Just expand it

$\frac{(a+b)^2}{4}-\frac{(a-b)^2}{4}=\frac{1}{4}\left((a+b)+(a-b)\right)\left((a+b)-(a-b)\right)=\frac{ab}{4}\cdot{4}=ab$
