Ancient Mayan Science of Number System, Script
The Mayas took base 20 in their number system. It is also known as a vigesimal system. They had 20 essential digits. The expression of very large numbers in a very easy manner was the advantage of this system. Further, there were two important symbols, a dot and a bar, to represent numbers. One was represented by one dot, two by two dots, three by three dots and five was represented by a bar. Concepts of addition and subtraction also prevailed.
The written language of the Maya was made up of about 800 glyphs, or symbols. Each one represented a word or a syllable, and could be combined with the others in an almost infinite number of ways. As a result, there were three or four different ways to write almost every word in the Mayan language.
The Mayans also were talented to build elaborate temples and great cities without the essential tools like metal. It is believed that the Maya were producing rubber products. According to a well known archaeologist, ""The Maya defined all phenomena of nature and their causes, and then represented them in the shape of human beings or animals. Their object was to keep for their initiates the secrets of their science"
