The temper of the math teacher
Look at the way you handle this kind of thing yourself. Actually, you can talk to your parents and tell them what you really think. First, it shows that the teacher's teaching method is a little unacceptable, which will affect your study and you can't learn knowledge better. Second, it shows that the teacher has a bad temper and no patience, and you can't get the knowledge you want from the teacher. Third, you can express a positive concept. For example, you can try to change my teacher to show that you want to learn well and avoid making mistakes. I say this because I don't want to learn, not because of the teacher. Before doing so, I should show my attitude, but I should also pay due attention to my tone. After all, it's your parents. Let them understand you and realize your mistakes.
