The abacus, also called a counting frame, is a calculating tool used primarily in parts of Asia for performing arithmetic processes. Today, abaci are often constructed as a bamboo frame with beads sliding on wires, but originally they were beans or stones moving in grooves in sand or on tablets of wood, stone, or metal. The abacus was in use centuries before the adoption of the written modern numerical system. It is still widely used by merchants, traders, and clerks in Asia, Africa, and elsewhere. The user of an abacus is called an abacist.
