Mayan Math

The Mayans, though it doesn't seem so, had a very easy numeral system. As opposed to our ten symbols, they used a mere three. Out of those three there is a horizontal line, a dot and a oval symbol.  Here is what they represent:
= 1

= 5

= 0 (or an empty place value)

Here are some Mayan numbers:
= 1  
= 6

= 2  
= 7

= 3  
= 8
= 4  
= 9
= 5


= 10
The Mayan number system is based on twenty, not ten like our number system is, so they don't use a different symbol until they reach the number 20.  You count by groups of 20 instead of groups of 10!

   

=11

   

= 20

Now for some really interesting numbers!

   

 
 

= 403   

  

= 690
