That’s not true not all maths teachers are like that at all. You’ll have different types of teachers. If you have a problem with them, you just say to someone about it and in my school, they’ll move you to another class or if a majority of students agree with you about a certain teacher, then the teacher will get replace with it so it’s your school that’s the problem rather than teachers in general as they should get better teachers and help you in any way. They’ll be more concerned if your parents talk to them. I’m sorry for saying this when you feel frustrated but i don’t want people to generalise teachers as my teacher has been teaching maths for 20 or more years and I don’t like how it’s being generalised. I’m sorry
