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.

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.
