Sumerian metrological numeration systems

Sumerian metrological numeration systems are among the earliest known numerical systems in history. The Sumerians, who lived in Mesopotamia around 4000 to 1800 BC, developed a sophisticated system for counting and recording quantities.

One of the most intriguing aspects of the Sumerian metrological numeration system is its use of a sexagesimal (base 60) system. This means that instead of the base 10 system we use today, the Sumerians counted in units of 60. This choice is believed to be related to the Sumerians' use of a sexagesimal system for measuring angles and time.

The Sumerian metrological system also featured a positional notation, similar to the system we use today, where the value of a digit is dependent on its position within a number. This allowed the Sumerians to represent large numbers efficiently.

Furthermore, the Sumerians used a combination of a decimal system (base 10) and a sexagesimal system in their numeration. This hybrid system is evident in the way they divided the hour into 60 minutes and the minute into 60 seconds, a practice that continues to this day.

Studying the Sumerian metrological numeration systems provides valuable insights into the origins of mathematical concepts that are still in use today. The Sumerians' innovations laid the foundation for the development of more advanced mathematical systems in ancient civilizations and continue to influence modern mathematics and metrology.
