Maya numbers are based around the number 20, so in Maya numbers , 20 is a 1 and a 0. So write a dot for the 1 and leave a gap below it. Then below the gap, draw a clamshell – the Mayan symbol for zero. To write numbers from 21–39, think of them as 20 plus something.
The Mayan and other Mesoamerican cultures used a vigesimal number system based on base 20, (and, to some extent, base 5), probably originally developed from counting on fingers and toes. The numerals consisted of only three symbols: zero, represented as a shell shape; one, a dot; and five, a bar.
Similar to the number system we use today , the Mayan system operated with place values. To achieve this place value system they developed the idea of a zero placeholder. The Mayan system is in base 20 (vigesimal) rather than base 10 (decimal). This system also uses a different digit representation.
A unit of the third position is worth 400 (20 x 20), so to write 401 a dot goes in the first position, a zero in the second and a dot in the third. Positions higher than the third also grow multiplied by twenties from the previous ones.
The Maya counting system required only three symbols: a dot representing a value of one, a bar representing five, and a shell representing zero . That the Maya understood the value of zero is remarkable – most of the world’s civilizations had no concept of zero at that time.
The Maya used the following names for their powers of twenty: kal (20), bak (400), pic (8,000), calab (160,000), kinchil (3,200,000) and alau (64,000,000).
The Babylonian cuneiform method of recording quantities, approximately 5000 years old, is among the oldest numeral systems in existence. They developed a base-60 (sexidecimal) system with numbers less than sixty represented in base-ten.
Two thousand years ago, the ancient Maya developed one of the most advanced civilizations in the Americas. They developed a written language of hieroglyphs and invented the mathematical concept of zero. With their expertise in astronomy and mathematics, the Maya developed a complex and accurate calendar system.
Pyramids were used not only as temples and focal points for Maya religious practices where offerings were made to the gods but also as gigantic tombs for deceased rulers, their partners, sacrificial victims, and precious goods.
Mysterious Decline of the Maya From the late eighth through the end of the ninth century, something unknown happened to shake the Maya civilization to its foundations. One by one, the Classic cities in the southern lowlands were abandoned, and by A.D. 900, Maya civilization in that region had collapsed.
So where we learn to count on our fingers, Maya children counted on their fingers and toes. The numbers above nineteen are indicated on the basis of their vertical position. The Maya used a vigesimal ( Base – 20 ) system, so each position is a power of twenty .
Corn (maize ) was the central food in their diet, along with vegetables such as beans and squash. Potatoes and a tiny grain called quinoa were commonly grown by the Incas. Avocados and tomatoes were mainly eaten by the Aztecs and Maya, along with a wide variety of fruit.
