Etymology of ABACUS
The word "abacus" originated from the Greek word "abax" or "abakon", which means "calculating table" or "calculating board". This Greek word, in turn, was derived from the Hebrew word "abq", meaning "sand". In ancient times, counting was often done using small stones or by drawing marks in the sand, and the abacus was a tool that evolved from these methods, consisting of a board with grooves or lines along which counters or pebbles were moved to perform calculations. The word "abacus" has been used in English since the 14th century to refer to this ancient calculation device.
