Located in modern-day southern Iraq, Sumer was the first civilization in Mesopotamia and arguably the earliest civilization in the world. The Sumerian number system, the first known number system that existed in written form, used the base 60. "Babylonian Mathematics and the Base 60 System."

The Babylonians used geometric shapes in their buildings and design and in dice for the leisure games which were so popular in their society, such as the ancient game of backgammon. [13], Base-60 number systems have also been used in some other cultures that are unrelated to the Sumerians, for example by the Ekari people of Western New Guinea. The sexagesimal system as used in ancient Mesopotamia was not a pure base-60 system, in the sense that it did not use 60 distinct symbols for its digits. For example, one hour can be divided evenly into sections of 30 minutes, 20 minutes, 15 minutes, 12 minutes, 10 minutes, 6 minutes, 5 minutes, 4 minutes, 3 minutes, 2 minutes, and 1 minute. He eventually conquered all of Sumer and also extended his influence beyond its boundaries. They never made the leap to using a zero symbol at the end of a number to eliminate the ambiguity completely. Thus, in the Babylonian system represented 3,600 plus 60 plus 1, or 3,661. Our open community is dedicated to digging into the origins of our species on planet earth, and question wherever the discoveries might take us. Indeed, we even have what appear to school exercises in arithmetic and geometric problems. The most familiar fact about the Sumerian system of numeration is that it was based on the number sixty, very much as ours is based on the number ten: thus just as our words twenty and thirty etymologically signify 2X10 and 3 X 10, so did the Sumerian words gesh-min and gesh-esh signify 60 X 2 and 60 X }. We usually think of reciprocals as number pairs like 2 and 1/2 that multiply together to equal 1. 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.

This way of counting is still used today for measuring time as 60 seconds per minute and 60 minutes per hour. From the number systems of these earlier peoples came the base of 60, that is the sexagesimal system.

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. Their system of numbering implies that they may have understood zero but, until further evidence is found, that remains largely conjectural.
