PROFESSIONAL TOOL - The soroban or counting tray is an abacus developed in Japan. It is derived from the ancient Chinese abacus (suanpan) that was imported to Japan in the 14th century. The abacus is a calculating tool that was used for centuries before the adoption of the written modern numeral system. The abacus is still widely used by merchants, traders and clerks in certain parts of the world such as Asia and Africa.
