TeenHelp - Professor apparently doesn't respect my learning disability

I talked to my teacher early in the quarter about whether there would be math on the tests. I did this because I have a severe math learning disability called dyscalculia. If a class does ask me to work with numbers, then I can talk to the office of disabilities and receive accommodations.
I asked him again the other day because on our lab was a simple division problem and I had thought heck, I should probably make sure just in case. He kind of mocked me with his answer. He said, "I already said there would be any, didn't I? What you don't believe me? Did you really think that was hard?"
I am used to being made for of for my inabilities while working with numbers, it happened all the time in elementary. So I shrugged it off and assured myself that is was probably a good idea to make sure and tried not to let it bother me.

Today in class he made a point of bring it up and saying some students were complaining about the simple math in the packet and how it wasn't even real math and that he had no sympathy as it was baby math. He complains about how short the classes are so I am unsure as to why he takes valuable class time to complain about one of his students concerns about the math in the packet. He seems like the kind of intellectual elitist that would tell me not to reproduce so I don't pass on my stupidity. I guess this is just kind of a rant? There isn't really anything I can do about him being a bully. Do you think I am being overly sensitive?
