The Mayans Had a Weird Number System

Discussing the number system of the Mayan civilization. They had a place value system that included zero! We mention the stone-set calendar script of the priestly class, but focus on the dots, bars, and shells of the common folk. We'll explain the vigesimal Mayan system, it's strange deviation from a standard base, the Mayan calendar, and do some arithmetic with the Mayan numerals. #maths #mathematics #history
