What is an Abacus?

What is an Abacus?

Article about the abacus, picture of abacus, the salamis table, counting boards, the chinese abacus, where to buy an abacus, and the history and origins of the abacus, and related links for further study. The abacus was one of the earliest counting devices in Asia and parts of Europe. It is still used today for arithmetic: adding, subtracting, multiplying and dividing.


Traditionally the Chinese abacus has 2 beads in the top section over the horizontal bar and 5 beads in the lower section, for each "column". The upper row beads could each represent one hand. The lower columns could represent the 10 fingers.

This picture of a black colored abacus shows an abacus with more depth to it than in the previous photograph. Many an abacus was home-made. In recent years an abacus could be purchased online.
