### About the Number 60 (sixty)

An article by the Arizona Republic's Clay Thompson indicated that Babylonians used the base-60 number system (sexagesimal). While looking at the base-60 number system, MathBabbler checked the Wikipedia and learned that the number 60 is a superior highly composite number. That discovery prompted MathBabbler to create this BAB.
