La numeración maya
The Mayas discovered the concept of zero around the year 36 BC. We use a base ten, or decimal, numeral system, meaning that we count by ten digits. The Mayas used a base twenty system, assigning symbols to numbers from zero to nineteen. It is possible that they developed this system from counting on fingers and toes. Numbers after nineteen were written vertically in powers of twenty.
