I kept telling my students that they were allowed to assume numbers had any order of magnitude they wanted. Hellenistic astronomers adopted a new symbol for zero, , which morphed over the centuries into other forms, including the Greek letter omicron, , normally meaning 70, but permissible in a sexagesimal system where the maximum value in any position is 59. [4] Another practical factor that helped expand the use of sexagesimal in the past even if less consistently than in mathematical tables, was its decided advantages to merchants and buyers for making everyday financial transactions easier when they involved bargaining for and dividing up larger quantities of goods. While we use the same numbersigns regardless of what is being measured, the Sumerians had a great number of signs, about 60 of them, grouped into a dozen or so measuring systems.

The Sumerians developed the earliest known writing system - a pictographic writing system known as cuneiform script, using wedge-shaped characters inscribed on baked clay tablets - and this has meant that we actually have more knowledge of ancient Sumerian and Babylonian mathematics than of early Egyptian mathematics. Its sexagesimal expansion begins 6;16,59,28,1,34,51,46,14,49,55,12,35 (OEIS:A091649). This advanced metrology resulted in the creation of arithmetic, geometry, and algebra.

Originally the Sumerians made small tokens out of clay to represent the items. [2][3] However, the Babylonian sexagesimal system was based on six groups of ten, not five groups of 12.
