=The Mayan Culture and Numbers.=  The Mayan culture was the first pre-columbian culture in designing a numerical system. This allowed them to advance in scientific studies as astronomers and mathematicians, where surprisingly, were very accurate.

Among the most important aspects of this culture, referring to their mathematical studies. Maya number system was one of the most complete and simple. It is characterized by the ability to combine 20-digit (The Mayans calculated with the hand fingers and toes), representing numerical quantities(1) through symbols like: A shell for zero, a dot "." for 1, and finally, a horizontal bar "-" for 5. Concerning the use of zero, the Mayans were the first to use it as a digit. This aspect is really incredible, because zero was used in Europe as soon as Asians and Arabs re-discovered it. Moreover, they also had notions of fractions and situations where we could define "Infinity**(infinite)**".All this, being isolated from the European continent. I think that the cause of the Mayan culture never became known in the ancient world, was the isolation of this culture with the European culture in the old continent. When the Spanish came to the "New World", they found a brilliant civilization, but the great mistake was master the Mayan culture and don't learnt anything of they.

According to studies**( Anthropological studies? . mathematicians**  **studies? . biologists studies?)(specifies)**, the Maya developed with the help of their number system, a calendar, whose accuracy is surprising. According to studies **(This is repeated, change it ; for example: other research (specifies the branch of science) says.....)**, the Mayan calendar, by using vigesimal system is more accurate than the Gregorian calendar.(2)

It really is a shame that European peoples (Spanish), without conscience and full of greed and aggression, whipped them so bright people, just for wanting to get "Money." Probably the fact that it was so bright, may not give them the privilege to not be overpowered by these hostile forces that ended his empire, and left buried in time great knowledge and discoveries.

EDWARD: You should say specifically what are the studies that say that the Mayan calendar is very precise and find another argument against previus argument and you support one of them. ** I agree. Plus there are some grammar mistakes that need to be corrected **
