Base 60, also known as sexagesimal, is a numeral system that uses sixty as its base. This means that it counts in groups of sixty rather than ten, as in the decimal system. The ancient Sumerians are credited with developing this system around 3000 BCE, and it has influenced how we measure time and angles today. In Base 60, numbers are represented using digits from 0 to 59. For example, the number 60 in Base 60 is represented as 10, similar to how 10 in Base 10 represents one group of ten. This system is still evident in our 60-minute hours and 360-degree circles, linking it to modern concepts of time and geometry.
