Don't worry. Every child is an angel, an angel raised by God in your home. Angels are smart.

As for the child's math test score of 0, it should be that the child has not yet understood and has no concept of mathematics. Take your time. Especially in primary school, it is mainly to cultivate children's healthy lifestyle (and habits), enterprising and kind mind, open-minded and determined personality and so on. As for knowledge, it is not too late to learn it later. Math problems are difficult, so don't look at them from an adult's point of view. Don't be confused by the propaganda of some training institutions, so as not to bring more pain to children.

For example, Ma Yun, who has been failing in mathematics, failed in the college entrance examination for the first time and reluctantly went to a regional normal school for the second time, so he had to learn a foreign language. But now, high flyers, who used to be in the same class, works for him.
