Numerical System
The Mayas used a positional base-twenty numerical system which only included whole numbers. For simple counting operations, a bar and dot notation was used. The dot represents 1 and the bar represents 5. A shell was used to represent zero. Numbers from 6 to 19 are formed combining bars and dots. Numbers can be written horizontally or vertically.
The value of a number depends on its position going from the bottom line upward in the configuration. The initial position (viz bottom line) has the value represented in the symbol. On the following line, the value of the symbol is multiplied by 20; on the third line from the bottom it's multiplied by 400, and each successive line is growing by powers of 20. That is to say, Mayan numerals use base 20. This positional system allows to calculate large figures, necessary for chronology and astronomy.

Famous quotes containing the words numerical and/or system:
“The moment a mere numerical superiority by either states or voters in this country proceeds to ignore the needs and desires of the minority, and for their own selfish purpose or advancement, hamper or oppress that minority, or debar them in any way from equal privileges and equal rights—that moment will mark the failure of our constitutional system.”
—Franklin D. Roosevelt (1882–1945)
“He is not a true man of science who does not bring some sympathy to his studies, and expect to learn something by behavior as well as by application. It is childish to rest in the discovery of mere coincidences, or of partial and extraneous laws. The study of geometry is a petty and idle exercise of the mind, if it is applied to no larger system than the starry one.”
—Henry David Thoreau (1817–1862)
