Detailed explanation-1: -Sexagesimal, also known as base 60 or sexagenary, is a numeral system with sixty as its base. It originated with the ancient Sumerians in the 3rd millennium BC, was passed down to the ancient Babylonians, and is still used-in a modified form-for measuring time, angles, and geographic coordinates.
Detailed explanation-2: -The theory is that the Sumerian and Babylonians were keen on the number 60 because 60 has many factors, including the first six numbers, one to six, but also 12, 15, 20, 30. This meant dividing by 60 often gives easy fractions. Much easier than say, the numbers 13 or 17.
Detailed explanation-3: -Babylonian mathematics used a sexagesimal (base 60) system that was so functional it remains in effect, albeit with some tweaks, in the 21st century. Whenever people tell time or make reference to the degrees of a circle, they rely on the base 60 system.
Detailed explanation-4: -The Babylonian number system uses base 60 (sexagesimal) instead of 10. Their notation is not terribly hard to decipher, partly because they use a positional notation system, just like we do. To us, the digit 2 can mean 2, 20, 200, or 2/10, and so on, depending on where it appears in a number.
