Babylonian number system was based on 60 (which is why we have 60 minutes in an hour and 360 degrees). 60 is dope because it has divisors 2,3,4,5,6,10,12,15,20,30 which is a lot of divisors.
Bee tee dubs Babylonians were like way ahead of their time math-wise. They were aware of Fourier for example.
