They began by creating symbols and signs for numbers and eventually identified 60 such numerical representations. Sumerians are famous for many achievements which include their writing system known as the cuneiform script, and the first known law code in history.

Instead, the cuneiform digits used ten as a sub-base in the fashion of a sign-value notation: a sexagesimal digit was composed of a group of narrow, wedge-shaped marks representing units up to nine (, , , , , ) and a group of wide, wedge-shaped marks representing up to five tens (, , , , ). The Sumerian language was eventually replaced by the Akkadian language around 2500 BC. And there's some logic to that.

Throughout their many centuries of use, which continues today for specialized topics such as time, angles, and astronomical coordinate systems, sexagesimal notations have always contained a strong undercurrent of decimal notation, such as in how sexagesimal digits are written. Over the course of the third millennium, these objects were replaced by cuneiform equivalents so that numbers could be written with the same stylus that was being used for the words in the text. A common theory is that 60, a superior highly composite number (the previous and next in the series being 12 and 120), was chosen due to its prime factorization: 2235, which makes it divisible by 1, 2, 3, 4, 5, 6, 10, 12, 15, 20, 30, and 60. 2 or 20 or 200, depending on the digits place, so could a Sumerian 2 c. 5000 BCE - 4100 BCE The Ubaid Period in Sumer .

While such context-dependent representations of numeric quantities are easy to critique in retrospect, in modern times we still have dozens of regularly used examples of topic-dependent base mixing, including the recent innovation of adding decimal fractions to sexagesimal astronomical coordinates.[4]. There have been various theories to explain these flood myths including a hypothesis that a meteor crashed into the Indian Ocean around 30002800 BC generating a mega-tsunami that flooded coastal lands.

Sexagesimal - Wikipedia Gutian dynasty ruled Sumer for roughly a century. Oh, well.. King of a utopian world? The legacy of sexagesimal still survives to this day, in the form of degrees (360 in a circle or 60 in an angle of an equilateral triangle), arcminutes, and arcseconds in trigonometry and the measurement of time, although both of these systems are actually mixed radix.[3]. Why do we need a symbol that literally means nothing?
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 }.

With Greek and Islamic innovations in geometry, it was discovered the 360 was not only the length of time of the earths ideal orbit but also the perfect measurement of a circle. However, the number 60 was represented by the same symbol as the number 1 and, because they lacked an equivalent of the decimal point, the actual place value of a symbol often had to be inferred from the context.
