A soroban is an abacus that is used for performing arithmetic calculations. It consists of a rectangular frame with rods or wires on which beads are strung. The beads are used to represent digits and are moved up or down to perform mathematical operations. The soroban is still widely used in Japan and other parts of Asia as a tool for mental calculation, and is also taught in schools as a method of learning arithmetic.
