Did Babylonians do math in base 60?

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.

How did Babylonians write 60?

But 60 and 1 would always be written identically. They never made the leap to using a zero symbol at the end of a number to eliminate the ambiguity completely. The oldest documented zero is surprisingly modern: it’s in a temple in India, and it dates from about 875 CE.

How do you count in base 60?

Actually counted into 60 on two hands. They would use each knuckle on one hand to count 12 and then count the number of 12 on the other. So you’d go 1 2 3 4 5 6 7 8 9 10 11 12. One set of 12.

Why do we use base 10 instead of base 60?

To be clear, base 60 has a big advantage over base 10: 60 is divisible by 3, and 10 isn’t. It’s easy to write the fractions 1/2, 1/4, and 1/5 in base 10: they’re 0.5, 0.25, and 0.2, respectively. But 1/3 is 0.3333…. Its decimal representation doesn’t terminate.
