It's treated as a singular noun by most, though, not a plural.
What would you say is better:
Mathematics is my best subject.
Or
Mathematics are my best subjects.
A lot of people, British or American, would say the first sentence sounds more natural than the second, which is why I say it's treated as a singular noun despite the 's' at the end. So math, without the 's, ' makes more sense grammatically.
Or so the argument goes.
English is practically a Google Doc shared by anyone that speaks English. Pretty inconsistent at times (to the point that it drives me crazy - especially possessive nouns that have "s" behind them), but it's gotten us thus far, so anything goes, as long as it works. Lulz.
