Although there was an image that the student is doing even at the Yokomine style kindergarten surely, since the abacus will expand the capacity of the brain, it is necessary to go to the top of the person for studying such as memory ability, concentration ability, information processing ability, etc. I think that it is a very useful learning work for building a foundation.
It is said to demonstrate outstanding power when working seriously from kindergarten senior to first grader.

It seems that the calculation mainly uses only the left brain
Calculating with an abacus, in order to use the left brain and the right brain at the same time
