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 in use centuries before the adoption of the written Hindu-Arabic numeral system and is still widely used by merchants and clerks in China, Japan, Africa and elsewhere.This vintage style abacus is built on top of a beautiful wooden case in ancient Chinese dragon & pheonix design. It has a deep compartment and a small drawer for storage. A English instruction booklet for bead arithmetic is included.
