The Maya (玛雅) number system(体系) appeared in the fourth century, which was about 1,000 years earlier than the time when the European number system was created. It is different from the Arabic number system with a base 10 (十进制). The Mayan system had a base 20. This system is believed to have been used because the Mayans lived in such a warm area and there was hardly a need to wear shoes, 20 was the total number of fingers and toes, so the system was workable. Therefore, there were two important numbers in this system. Besides 20, the other important number is 5, which had a connection with the number of fingers and toes on one hand or foot.
The Mayan system used two symbols (符号). A dot (.) was used to mean the units ( one to four) and a dash (—) meant five. The Mayans were also the first to create symbols of nothing ( or zero). The most common symbol was that of a shell but there were several other symbols. It is interesting to learn that with all of the great experts on Maths and scientists in ancient Greece and Rome, it was the Mayan Indians who came up with this symbol zero or nothing. The following picture is a form of different numbers and how they would have been written.
From further study, people found that the 360 day calendar(日历) also came from the Mayan. They actually used base 18 when they made the calendar. Each month included 20 days with 18 months in a year. This left five days at the end of the year which was month in itself, full of danger and bad luck. In this way, the Mayans had invented the 365 day calendar.
