What is the difference between an abacus and an electronic calculator?
With an electronic calculator, the child provides the input (numbers, addition or subtraction), and the calculator provides the output (numbers). But in the case of the abacus, the child converts the numbers into beads (input), manipulates the beads (processing), and brings out the result (output). After finishing our instruction books and with daily practice, your child will be able to do the arithmetic calculations MENTALLY very soon.
