My math teacher is an asshole?

[Bob]

So basically my math teacher hates me for no apparent reason. I am in 10th grade and he is just out of control. I would consider myself to be a good student and i am not disruptive during class. He seems to always victimize me for no reason, for example i will be sitting in the classroom during one of his lessons and out of nowhere he will insult me in some way. He always calls on me for the hard questions and yells at me when I get it wrong but when he asks another student in my class he doesn't even care he just tells them to "get it right next time". Even If I get the answer right he will just find some minor flaw in my answer like that i didn't put the word "inches" next to my answer or something like that and go overboard with it and lecture about it for over 10 minutes. I get good grades in his class and i don't know why he hates me. Can anyone think of why he would hate me and how I can deal with it?
