10 is two lines 11 is one dot over two lines 12 is two dots over two lines etc... 20 is one dot over a shell. 21 is one dot over one dot 22 is one dot over two dots etc... 39 is one dot over four dots over three lines 40 is two dots over a shell 41 is two dots over one dot 42 is two dots over two dots etc... 60 is three dots over a shell etc... 80 is four dots over a shell etc... 100 is a line over a shell The Mayan number system is a base-20 system. A dot is 1, a line is 5, and up to 19 you can write in one "digit". As soon as the number increases over 20, it goes up into the second "digit" and you stack a dot (this time multiplied by 20) over a shell shape (worth zero). It's just like our number system, except our number system uses a base-10 system.
