> When you say "maths", how many do you mean?
All of them.
All of them.
I think its funny that terms like math v maths come about very organically and then after the fact everyone feels the need to back into a reasoning that was likely never there. Obviously neither are wrong because they are the "correct" way for a given dialect/region etc.
No, that's arithmetic (which is always singular, amusingly).
I find it generally amusing to examine the differences between U.S. and British English and quite often get confused over whether I should be using "licence" or "license". It's the little quirks of language/spelling that make it interesting. (Though english, I'm a big fan of some of the U.S. contractions such as "y'all'd've")
I would say "math" is an objectively better shortening of "mathematics" as it preserves the singular collective meaning than "maths" which preserves more of the incidental textual form.
We Americans use the phrase "do the math," which means to go figure something out, not necessarily arithmetically.
Is there a similar phrase for the Brits? As in "do the maths?" Which seems unlikely. As such, I'd expect those using British style English to have different phrase for the same thing. Is that the case? If so, what might it be?
