The calculation is too boring to guide correctly, mainly because of the teacher's problem.

I have never had this problem, and I have been interested in mathematics since I was a child.

I am deeply impressed by several primary school math teachers, and I feel that the teachers are becoming more and more impetuous.

Primary education is very important, children are highly plastic, and teachers' every move has a far-reaching impact on children's life.

Of course, family education is the same, but no parents like others to criticize themselves. Parents usually ignore their own mistakes, hehe.
