not really. but i'll take your word for it. I'll never use it without sounding like a twat, but happy to stand corrected. And just to clarify, I never denied the existence of the word math. I was skeptical that math as a singular of the plural maths was real, mathematics being a noncountable noun it makes no sense to have a singular. You can't say one mathematic, two mathematics, so why would the short forms change the meaning? Are you making math = single calculation up?
