Which concept did the maya understand before Europeans did the number zero a. architecture b. calendars c. hieroglyphics d.

Answer 1

The correct answer is not explicitly listed, but the concept that the Maya understood before Europeans did is the number zero. The Maya civilization developed a sophisticated numerical system that included the concept of zero as a placeholder, which was crucial for their calculations and calendar systems. Therefore, while the options provided don't directly include "number zero," the closest related concept to this understanding could be b. calendars, as the Maya's use of the zero was significant for their complex calendar calculations.
