About this app
The abacus is a form of manually operated calculation aid with a history of more than 2,600 years and is an important invention in ancient China. Before the advent of Arabic numerals, the abacus was a calculation tool widely used in the world.

The Abacus APP simulates a traditional Chinese abacus with two up and down five beads, aiming to provide a simple practice tool for those interested in abacus.
