I've seen quite a few posters here use "maths", plural of "math". I never heard or saw that before I started reading posts here, and I was wondering just what dialect is this. Some Brit posters use it, I think. Is this a Britishism? Do any American speakers here use "maths"? How about Aussies?

Thinking about it, the full term, mathematics is plural, but the short "math" has always been singular. I say "Do the math", not "Do the maths". Don't get me wrong, I'm not complaining. I mean, if that's considered correct in your native dialect, more power to you. But it just seems odd to me and sort of sticks out when I read it.
