Cuneiform Numbers - Numberphile

Numberphile9 minutes read

Babylonian Cuneiform Numbers, the oldest number system from around 3000 years BC, used wedge marks in mud on small tablets based on a sexagesimal system with symbols for 1 to 59 and a unique symbol for 60, adopting zero later on. The system's choice of base 60 is still a mystery, potentially influenced by the divisibility of 60 and the natural tendency to count in base 10 due to fingers.

Insights

  • Babylonian Cuneiform Numbers originated in the Sumerian civilization around 3000 years BC, employing wedge-shaped script on small tablets to represent a sexagesimal system with symbols for 1 to 59 and a unique symbol for 60.
  • The Babylonian number system, developed in Babylon by 2000 BC, utilized additional columns to represent numbers beyond 59, initially lacking a symbol for zero but later incorporating two diagonals to denote zero in certain positions, showcasing a unique blend of mathematical innovation and practicality.
