| | Maya Mathematics, simple and ingenious. Fast to learn, easy as a game. |
 | | The decimal mathematical system widely used today originated by counting with the fingers a person has. |
| | Just as the decimal system goes by 1, 10, 100, 1000, 10000, etc., the Maya vigesimal system goes 1, 20, 400, 8000, 160000, etc. While in the decimal system there are ten possible digits for each placeholder [0 - 9], in the Maya vigesimal system each placeholder has a possible twenty digits [0 - 19]. |
| | Thus when writing vertically the vigesimal positioning system, to write 20 a zero is placed in the first position (base) with a dot on top of it, in the second position. |
