Maya numbers were written in a bar-and-dot system:
bars had a value of 5 and dots 1. The counting system was based on
20, rather than the 10-based decimal system we use today. A great achievement
of this counting system was its use of a placeholder, or "zero."
For larger numbers, they used place notation just
as we do, except that Maya numbers could be written horizontally
or vertically, with values increasing from right to left or from
bottom to top.
The Maya wrote 22 as
one 20 + 2 ones)
and wrote 49 as
two 20s + 9 ones)
