They used this when they came up with 60 minutes in an hour and 360 degrees in a circle. Because there was no symbol for zero it is not always immediately obvious how a number should be interpreted, and its true value must sometimes have been determined by its context. The base isn't what makes calculations in base 60 difficult, it's the fact that mathematical culture of the people who made it is so different from ours. No joke, I have talked to kids who are so removed from realityby the social engineering they actually believe things like this. [24] This notation leads to the modern signs for degrees, minutes, and seconds.

The Sumerian sexagesimal system used ten as a sub-base. At night, whew, that's a bad one unless it's a full moon (I also have a moondial alarm clock but it doesn't always work, poor calibration), and being 86 I can't always recognize the time when to empty my bladder and being disoriented often pee in the closet. This idea of using position to arrange integers, known as the principle of position, is the first known use of such a system, the basis of our decimal system. In ancient times, humans would determine the time by using devices made of sand, stone, shadows, wheels, and more.
