There is a little Babylonian counting tutorial. One of their problem is they have no zero. I think, it is because the things they counted have no zero point, either. The Babylonian numbers rooted in endless conceptions as time and circle. There 60 minutes in an hour and 60 seconds in a minute. There are also 360 degrees in a circle. (Yes!  We’ve got it from them!)

And, as I’ve suspected, there are gaps in my knowledge of ancient history; however, here what I found on The Abelian Grape blog  :

  The ancient Chaldean (Babylonian) number system was base 60, and that, because when multiplied by the 6 sides of the earth hexagon, equals 360 degrees, the subdivision of the earth for ancient mapping which traces back to the methodology to measure the earth by the rate of precession, 72 years/degree, the number of conspirators who killed the ancient Egyptian god of the underworld, Osiris, as precession time marched on.
