Abacus mental arithmetic is calculated according to the principle of abacus calculation, while abacus addition and subtraction calculation is calculated from high position to low position, and vertical calculation in mathematics is calculated from low position to high position. Looking at the opposite direction so thick, some people say it's chaotic. In fact, we asked the children who had studied abacus mental arithmetic, and none of them said they would be confused. On the contrary, primary school teachers and some parents are always worried. In fact, this is unnecessary. Even if some children feel a little confused, as long as they learn abacus well, there will naturally be no such problems.

Facts speak plainer than words. The study of mental arithmetic is beneficial and harmless to the study of mathematics, and can be transferred to other disciplines. I hope you can send your children to study and keep practicing! At present, I am learning to calculate skillfully and quickly, and I am doing well. If I change it for him at this time, I am worried that it will bring bad influence to the child. As the saying goes, everything will end.
