Agriculture Economy based on Agriculture Maya means : those who cultivate the corn No metal tools
Science Astronomy development Development of Matematics tools to calculate the movement in the sky notably the moon and sun. Master the 0 numeral Solar year very precised times is counted in days, period of 20 days, in years of 360 days
NO SPECIFIC SYMBOLS FOR NUMBER GREATER THAN 19 INSTEAD… SYSTEM OF POSITION
The Maya were not using the same system to count objects and numbers…. Objects Unit of Time 20x20x20x20 20x20x20 20x20 20 1 20x18x20x20 20x18x20 20x18 20 1
Counting from 20… Numeration is one of POSITION Every number more than 20 needs to be decomposed into the sum of powers of 20 EX : 21= 20x1 +1 79=20x3+19 If a number is more than 20 than we need to write it on a vertical column. The position of the number determined its value We read the number from top to bottom and the power of 20 decreases.
Think of floors The 2 nd floor is a multiple of 20 First floor Second Floor
