[[Image:Babylonian numerals.svg|450px|thumb|Babylonian cuneiform numerals]]
The [[Babylonian cuneiform numerals]] had a [[numeral system|base]] of 60, inherited from the Sumerian and Akkadian civilizations, and possibly motivated by the large number of divisors that 60 has.{{Citation needed|date=December 2022}}  The [[sexagesimal]] measurement of time and of geometric angles is a legacy of the Babylonian system.

The number system in the [[Mali Empire]] was based on 60, reflected in the counting system of the [[Maasina Fulfulde]], a variant of the [[Fula language]] spoken in contemporary [[Mali]].<ref>{{cite book|last=La Fontane|first=Jean sybil|year=2004|title=The Interpretation of Ritual: Essays in Honour of A.I.
