The abacus is a hand-operated calculating tool used for centuries in various cultures, including the ancient Near East, Europe, China, and Russia, before the widespread adoption of electronic calculators.The Chinese abacus typically consists of beads strung on wires or rods within a frame, with a divider separating the beads into upper and lower sections. Users perform mathematical calculations like addition, subtraction, multiplication, and division by manipulating the beads according to specific formulas.
