I have a mother who is a teacher. She has checked my homework every day since primary school. As we all know, in primary school, there is a unit table behind the language of each unit, which is the teacher's compass. Every time after school, I will assign this homework and write it many times. My parents will check it and sign it. This is a very simple homework, it just takes some time, but for me, it takes some time. As a teacher's mother, I should not only finish this homework, but also write carefully, one by one, and tell me that this is also a way for you to practice writing. The same is true of mathematics. It won't go wrong. My mother is a math teacher.
