The abacus, also called a counting frame, is a calculating tool used primarily in parts of Asia for performing mathematical processes. The abacus was in use centuries before the adoption of the written modern numeral system and is still widely used by merchants, traders and clerks in Asia, Africa, and elsewhere.
