Which ancient civilization is credited with developing the sexagesimal (base-60) numerical system, a mathematical concept still used today for measuring time (60 seconds, 60 minutes) and the geometry of a circle (360 degrees)?

💡 Explanation:

The Sumerians, who inhabited Mesopotamia, developed the base-60 system for mathematical and astronomical calculations. This system proved highly effective for calculations involving fractions and divisions, leading to its adoption for angular measurement and units of time.
