The Math of the Maya A Base 20 System |

**T**he Maya
used a base 20 system. Learning their math is simple and fun. Read the examples
below, then take the math test to see how well you do with the math of the Maya.

In the math of the Maya, a dot was used to symbolize 1 (one), two dots for the number 2, three dots for 3, and four dots for 4.

The number 5 (five) was represented by a bar. For the number 10, there were two bars; 15 was three bars; and 20 was four bars.

In the example above, one dot (the
number 1) plus two dot (the number 2) equals 3 dot (the number 3). So, 1 plus
2 equals 3.

In the example above,
one dot (the number 1) plus one bar (the number 5) equals the number 6. So,
1 plus 5 equals 6.

In the example above,
four dots (the number 4) plus two bars (the number 10) equals the number 14.
So, 4 plus 10 equals 14.

In the example above,
the first symbol is the number 9 (4 plus 5) , then add the second symbol (the
number 10) for a total of 19. So, 9 plus 10 equals 19.
