The abacus is a square-shaped instrument made of wood which consists of ten different wires or strings placed in parallel. Each of these strings has ten balls that have mobility. It is an instrument that helps people to perform simple calculations. It was a widely used instrument in antiquity, and was used to teach students simple mathematical operations, such as multiplying, dividing, adding, and subtracting. Some historians believe that the abacus was the first instrument created to perform calculations. Invention and technological innovation have relegated the use of the abacus and caused it to lose popularity in schools and homes, where it was previously used to educate children.
