THIRD PART OF BRAILLER ÁBACO

Hello to all the steemit community, today we will explain how the abacus is used, it is a very easy system and this information is very important since we talk about symbols, braille writing and writing on the abacus. I'll give you a guide and illustrations of how to learn how to use them and I hope you like the whole steemit community.

This does not mean that if the child uses other fingers, the I'm doing inadequately.
