What is an abacus?

An abacus is a traditional counting tool that has been used for centuries in various cultures around the world. It consists of a wooden frame with a series of rods or wires, each containing a number of beads. The beads are typically moved back and forth along the rods to represent different numbers in a numerical system. The abacus is primarily used for basic arithmetic calculations, such as addition, subtraction, multiplication, and division. It is considered a simple and effective tool for developing mental math skills and is often used in schools to aid in teaching mathematical concepts. While the abacus has been largely replaced by electronic calculators and computers, it still holds cultural and educational significance in many societies.
