Mental abacus

The mental abacus is a technique used for performing mathematical calculations mentally, often inspired by the traditional Chinese abacus. Practitioners of mental abacus can visualize an abacus and use it as a tool to facilitate their calculations, even though they are not physically manipulating an actual device. The technique is frequently taught to children as a way to develop their arithmetic skills, enhance memory, and improve concentration. It is believed to foster both computational speed and accuracy, making mental math easier and faster.
