The Mayans made important contributions to astronomy, mathematics, and architecture through their accurate calendar, use of the number zero, stepped pyramids, and belief system that divided the world into the underworld, earth, and sky. They were skilled in mathematics and astronomy, developing sums up to one hundred million and using the number zero by 36 BC.
