The abacus (plural abaci or abacuses) also called a counting frame, was in use in the ancient Near East, Europe, China, and Russia, centuries before the adoption of the written Arabic numeral system.The abacus essentially consists of a number of rows of movable beads or other objects, which represent digits. One of two numbers is set up, and the beads are manipulated to implement an operation involving a second number (e.g., addition), or rarely a square or cubic root.
Although today calculators and computers are usually used instead of abacuses, abacuses still remain in common use in some countries. Merchants, buying traders and clerks in some parts of Eastern Europe, Russia, China and Africa use abacuses, and they are still used to teach arithmetic to children. Some people who are unable to use a calculator because of visual impairment may use an abacus.
