History says that the first time humans created a calculating tool using a pebble stone placed on the ground, or a string that was summed up in each strand, or also with a branch of a tree branch.
Then the Chinese create a calculating tool sipoa, the measuring instrument that originally in the form of pebbles. Sipoa in the form of stones or seeds stuck in the middle of his then stretched with wood or wire in a box.

Sipoa breaks through civilization for the sake of civilization, able to survive centuries as a counting tool. Even today chinese and japan are still using it, another example of elementary school children still trained to count using a cockroach.
The ica nation that lives peru (south america) centuries ago also has a calculating tool called quipus, in the form of a rope wrapped. Each slug has a certain value
