WTNC 13 Digital Abacus with Reset Button for Students 10 Inch Japanese Chinese Soroban School Calculator Math Counting Tool (Yellow)

Introduction: An abacus, also called a counting frame, is a calculating tool used primarily by Asians for performing arithmetic processes. Nowadays, abaci are often constructed as a wooden frame with beads sliding on wires, but originally they were beads or stones moved in grooves in sand or on tablets of wood, stone, or metal. The abacus was in use centuries before the adoption of the written modern numeral system and is still widely used by merchants and clerks in China, Japan, Africa, India and elsewhere. Suanpan can be used for functions other than counting. Unlike the simple counting board used in elementary schools, very efficient suanpan techniques have been developed to do multiplication, division, addition, subtraction, square root and cube root operations at high speed. The user of an abacus is called an abacist; he or she slides the beads of the abacus by hand.
