How did the Maya and Aztec civilization use science and math?

The Mayan's were the first people to discover zero and created an accurate calendar with 365 days.

Achievement

Significance

The Mayans figured the concept of zero 1,000 years before the Europeans did.

They had a vital understanding of math that most of the world did not understand at that time. They had a dot for one, a line for ten, and a shell symbol for zero. They also had a similar place value as us but counted by 20’s instead of 10’s.

Their calendars were precisely accurate including 365-days a year. That also helped track the cycles of planets/the solar years.

They tracked astronomical activities to predict the future ( priests/astronomers noted eclipses to then appease the gods by making ceremonies to make sure a disaster won’t occur because the (eclipse)  is a bad omen). They were aware of time and seasons. Which they then made into accurate calendars. Which is actually quite admirable really.

Explanation: I did a whole essay about the Inca, Mayan and Aztecs a week ago. LOL

i believe the answer is: returns on investments, no wages

people who belong in upper class society would most likely get there by obtaining multiple source of income, which a certain percentage of ownership for businesses. since most of them are job creator, they would most likely get their money from profit, not wages.
