Abacus Trial [at home]
The abacus, a unique counting tool invented by ancient Chinese people, has faded out in most areas of China, as calculators and computers are widely used in modern times. But in the long history until only twenty years ago, the abacus has long been an important calculation tool for every household, not to mention accountants and dealers. The abacus is a rectangular wooden frame. Inside the frame, there are usually at least seven vertical rods and a horizontal beam. Each rod represents a different numerical digit. After setting the digit, an operator can move the beads up or down towards the beam to do the calculating. Because of this, abacus computations are also called bead computations. To use the abacus well, one must recite a concise formula by which the calculations of addition, subtraction, multiplication and division can all be simplified into the acts of moving the beads.

This virtual course will teach lightning-fast calculation techniques for addition, subtraction, multiplication and division. Our dedicated instructors make learning enjoyable and ignite a passion for math.
