Math Teacher

Math Teachers could either be the best or the worst, throughout my years at school my math teachers were pretty chill, till I hit 9th grade. At first, I thought he was cool but as the days went by, he was the worst, he would embarrass students who didn't get to answer his questions and he threatened to break my friend's finger if he didn't start counting because he couldn't solve a math problem. It was hard for me to focus on math class because I kept overthinking if he's gonna call me again and embarrass me in class. In online classes, he removes the people on the call that doesn't turn on their cameras, he doesn't care if they have an excuse that their cameras are broken, he just removes them. Please tell me if ur math teachers are like this.
