Another mathematical calculation that is performed by users, student and pupils of the abacus is that of multiplication. It is important that people, especially the children or kids who use the abacus, that they know exactly how to perform this basic abacus math for kids calculation. This will help them with all their future basic math problems and will stand them in good stead for their future maths studies at primary, secondary and tertiary levels. It is also important that users of the abacus are taught by experienced and qualified abacus instructors or tutors as everybody needs to learn how to use and apply the abacus to math calculations effectively and efficiently. This is all of specific educational importance to all the private math tutors and parents of the enrolled children as well as the children who attend the abacus math lessons at any of the two Math Genie schools in the state of New Jersey in the United States of America. Simple multiplication, like the example of multiplying five by seven to equal thirty five, is done as repeated addition. It is useful to keep a running tally of how many times you have added 7. The unused columns on the left hand side of the abacus can be used for this. Two digit or higher multiplication is done just as with pencil and paper. It requires memorizing the times tables or having a second abacus to do the simple multiplication. The unit’s column is done first. The results of the multiplication of the unit of the bottom number and the tens of the top number are stored in the second column. Keep in mind the process of pen and paper multiplication, and the abacus presents no real difficulty. Division is done as repeated subtraction - again keeping a tally of how many times you have subtracted. If you would like a little challenge, try doing calculations in other number systems. The Chinese abacus is already useful for base 2 and base 16 calculations. Each rod on the Chinese abacus has 16 possible values because that was the unit of weight in China. Because of this, you can also use the Chinese abacus for hexadecimal calculation. And if you ignore the earth beads, you can use the heaven beads for binary calculations. The best way to learn about the abacus is by doing. Get a stack of pennies or buttons, clear a spot on the kitchen table and try out some sums! And as you are busily calculating away, keep in mind that you are continuing a two thousand year tradition that is still alive and well today.
