Probably of Babylonian origin, an abacus is a calculating instrument that uses beads that slide along a series of wires or rods set in a frame to represent the decimal places. It is the ancestor of the modern digital calculator.
Later, loose objects in columns were replaced with beads that could slide along parallel rods. There is an unproved information, that similar to abacus device was used in Babylonia as early as 2400 BC. The word abacus itself is a Latin word, which comes from Greek Î¬Î²Î±ÎºÎ±Ï (board or table).ater, loose objects in columns were replaced with beads that could slide along parallel rods.
