With abacus, you can make addition, subtraction, division and multiplication – all sound very easy. The easiest one to understand is addition and the method is very simple.
For example, if you want your kid to add 5 + 2, you can move five beads to one side of the frame in one row and then move two beads of the second row to the other side and ask your child to show you the total number in the third row.
You can also ask them to calculate the total number on their fingers before they actually move the total number of beads. Once your children learn addition, you can go on teaching them other methods before they start going to the primary school.
