Maya Mathematics

Instead of ten digits like we have today, the Maya used a base number of 20. (Base 20 is vigesimal.) They also used a system of bar and dot as "shorthand" for counting. A dot stood for one and a bar stood for five. In the following table, you can see how this works. 0 1 2 3 4

5 6 7 8 9

10 11 12 13 14

15 16 17 18 19

Because the base of the number system was 20, larger numbers were written down in powers of 20. We do that in our decimal system too: for example 32 is 3×10+2. In the Maya system, this would be 1×20+12, because they used 20 as base.

Numbers were written from bottom to top. Below you can see how the number 32 was written:

20's (1) 1's (12)

It was very easy to add and subtract using this number system, but they did not use fractions.

It was very easy to add and subtract using this number system, but they did not use fractions. Here's an example of a simple addition:

8000's 400's 20's + = 1's

9449 + 10425 = 19874 

As you can see, adding is just a matter of adding up dots and bars! Maya merchants often used cocoa beans, which they laid out on the ground, to do these calculations.
