Babylonian Sexagesimal Math Tablet - Historical Calculation Example #1691095 (License: Personal Use)

This image displays two lines of Babylonian cuneiform numerals using the sexagesimal (base-60) system: “14.20 + 15.9 = 71.9” and “20.20 - 18.9 = 1.2”. Each numeral combines symbols for units and tens, reflecting how Mesopotamian scribes performed complex arithmetic over 3,700 years ago. The notation predates modern decimal systems and underpins our current time and angle measurements.
