So, just saying...
Usually you- or rather, I, don't learn multiple types of math in a year, so it would be math, as in I am learning THIS TYPE OF math...
You wouldn't hear someone saying "mathematic" you would say "mathematics" so that's why it should be maths not math. And it doesn't have to be plural either. For example the word for mouse in French "souris" is both singular and plural.
