A Chinese Calculator is a type of calculating device that has been used in China for centuries. It is also known as an ABACUS, which is a six-letter word. The ABACUS is composed of a frame with beads strung on wires, and it is used to perform mathematical calculations by sliding the beads along the wires. It is still used today in some parts of the world, particularly in East Asia, as a tool for teaching basic arithmetic.
