An abacus is a tool that has been used for calculations since ancient times. It consists of beads strung on a wooden frame, allowing users to perform calculations.
Calculators are widely used these days, but using an abacus is said to improve mental calculation skills. In Asia, many schools still teach how to use an abacus.
