The abacus was a calculator invented sometime between 1000 BC and 500 BC in China, often constructed as a wooden frame with beads sliding on wires. It was used centuries before the adoption of the Hindu-Arabic written number system and is still widely used by merchants and employees in China, Japan, Africa, and elsewhere. The abacus is also widely used in teaching counting and mathematics. This standard set is perfect for practical use and teaching children.
