Abacus Mathematics and Smart Brain 

From the Greek word abax, meaning "calculating board" or "calculating table," the Chinese abacus was invented during the Yuan Dynasty, 1280-1368 AD. Often referred to as the first computer, the abacus is used to add, subtract, multiply and divide, as well as figuring fractions and square roots. In certain Asian communities, abacuses are still being used to calculate invoices.

The new Abacus Mathematics system is very rapidly spreading and it is good to improve the child's Smart Brain.
