ROUND 3

Base 20

Are you feeling smart? Now that you have the base-10 system down, you will have no problem figuring out the Maya base-20 system.

In the base-20 system, numbers are written in units of 1s, 20s, 400s, 8,000s, and so on. This system developed from the fact that humans have 10 fingers and 10 toes.
