The abacus is a calculating tool which has been used since ancient times. It was used in the ancient Near East, Europe, China, and Russia, centuries before the adoption of the Hindu-Arabic numeral system. The exact origin of the abacus has not yet emerged. It consists of rows of movable beads, or similar objects, strung on a wire. They represent digits. One of the two numbers is set up, and the beads are manipulated to perform an operation such as addition, or even a square or cubic root. https://en.wikipedia.org/wiki/Abacus
Yes, I've purchased and used an abacus for calculating. People who are adept with an abacus can do some calculations faster than with a calculator, due to a fewer number of steps required to do certain tasks. (I believe these are more to do with accounting related tasks?)
