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.
Here's an example of a simple addition:

8000's
400's
20's		+		=
1's
	9449	+	10425	=	19874

The Mayans devised a counting system that was able to represent very large numbers by using only 3 symbols, a dot, a bar, and a symbol for zero, or completion, usually a shell. The chart above shows the first complete cycle of numbers. Like our numbering system, they used place values to expand this system to allow the expression of very large values. Their system has two significant differences from the system we use: 1) the place values are arranged vertically, and 2) they use a base 20, or vigesimal, system. This means that, instead of the number in the second postion having a value 10 times that of the numeral (as in 11 - 1 × 10 + 1 × 1), in the Mayan system, the number in the second place has a value 20 times the value of the numeral. The number in the third place has a value of (20)², or 400, times the value of the numeral. This principle is illustrated in the chart below.
