Unary numbers

The simplest possible numeration system is base-1, which uses a single repeated symbol.

There are some human languages which have no numbers at all, making it necessary to use a "unary system" in speech - that is, to say "berry and berry and berry" instead of "three berries".

The unary origin of written numbers is clearly visible in Sumerian, Egyptian, Chinese, Attic, Roman and Mayan numerals. It can also be seen in modern Hindu-Arabic numerals (count the number of edges in 1, 2 and 3!)
