**How did astronomy and mathematics help Mayan society?** The ancient Maya achieved an unparalleled understanding of astronomy. **They developed an advanced system of mathematics that allowed them to create a set of calendars unrivaled in the ancient world**.

**How did the Mayans contribute to astronomy?** Maya astronomer-priests looked to the heavens for guidance. They used observatories, shadow-casting devices, and observations of the horizon to trace the complex motions of the sun, the stars and planets in order to observe, calculate and record this information in their chronicles, or “codices”.

**What did the Mayans contribute to math?** The most noteworthy trait of Mayan mathematics was **an awareness of zero**. The concept of zero in mathematics was unknown in most places during the time of the early Maya, with the Gupta Empire in India being an exception. Zero days and zero years exist in Mayan calendars, unlike the standard Gregorian calendars.

**Did the Mayans invent astronomy?** **The Classic Maya in particular developed some of the most accurate pre-telescope astronomy in the world**, aided by their fully developed writing system and their positional numeral system, both of which are fully indigenous to Mesoamerica.

## How did astronomy and mathematics help Mayan society? – Additional Questions

### Who invented astronomy?

**The Ancient Greeks** developed astronomy, which they treated as a branch of mathematics, to a highly sophisticated level. The first geometrical, three-dimensional models to explain the apparent motion of the planets were developed in the 4th century BC by Eudoxus of Cnidus and Callippus of Cyzicus.

### What did the Mayan invent?

They were gifted designers and architects who built grand structures including **royal residences, galactic observatories, sanctuary pyramids, straight roads, and canals**. The Maya also invented elastic a long time before the process of vulcanization, or rubber-making, was discovered.

### When did the Mayans invent astronomy?

The sun, moon, and planets—Venus, in particular—were studied by the Maya. The heyday of Maya astronomy was in the **8th century CE**, and Maya daykeepers published astronomical tables tracking the movements of celestial bodies on the walls of a special structure at Xultun, Guatemala in the early 9th century.

### Did the Aztecs study astronomy?

For the Aztecs, like for many other civilisations, **astronomy was a study closely associated with religious significance and a strong moral code of behaviour**. Aztec astronomy also played an important role in later history in relation to the emancipation of Mexico from Spanish colonial rule.

### What constellations did the Mayans discover?

### What is Mayan math?

The Maya used the vigesimal system for their calculations – **a system based on 20 rather than 10**. This means that instead of the 1, 10, 100, 1,000 and 10,000 of our mathematical system, the Maya used 1, 20, 400, 8,000 and 160,000.

In their numeral system, the ancient Maya only used three symbols to represent all numbers. A dot has a numerical value of 1, a line (or bar) a numerical value of 5 and a shell has the value of 0.

### How did the Mayans think the universe was created?

The world consisted of the sky and the sea. The gods resided in either the sky or the sea and realized the great potential for the emptiness. **One god from each region, Plumed Serpent from the sky and Hurricane from the sea, came together to create the world.**

There was thus no need for the average person to understand the calendar, and it could be as elaborate as the priests wanted.

To solve this problem **the Egyptians** invented a schematized civil year of 365 days divided into three seasons, each of which consisted of four months of 30 days each.
