Frequently Asked Questions
What is the Sumerian number system?
The Sumerians (and later Babylonians) used a base-60 (sexagesimal) system. It originated around 3000 BCE and is the reason we have 60 seconds in a minute and 360 degrees in a circle.
How do I convert decimal to Sumerian?
Divide the decimal number by 60 repeatedly. The remainders become the digits in each column, reading from right (units) to left (60s, 3600s).
What is the difference between Sumerian and Babylonian math?
Sumerian math laid the foundation with the base-60 system and tokens. Babylonian mathematicians (who came later in the same region) refined this into a fully positional system and developed advanced algebra and geometry.
