A: What time is your math/Math class?
B: At eleven forty-five.
Do we have to use 'math' or 'Math'?
And is it a common noun or a proper noun?
You use "math" when you're making a general reference to the class, whether it's Algebra I or Geometry or whatever.
You use "Math" when it's part of the formal name of the course. "When I was a senior in high school, my math course was called Math IV."posted by Writeacher
If "Math" is the specific title of that particular class, then use the capital. Otherwise the lower case is fine. However, specific titles typically include some numerical designation, such as "Math 101."
I hope this helps. Thanks for asking.posted by PsyDAG
