Number Systems Ancient to Modern 2: the Babylonians | Sociology and Pure Maths | N J Wildberger

The Old Babylonian arithmetical system was a base 60, or sexagesimal floating point system -- an ancient precursor to the Hindu-Arabic base 10 system that we use today. However there is a big difference, due to the fact that 60 has a factor of 3, while 10 does not! Why should that be so im

Division is the most difficult of the four basic arithmetical operations. Here we shed light on the Old Babylonian approach to division in their sexagesimal or base 60 system, by translating their arithmetic to the new base 100, or centimal" . We have some critical things to say about our
