That may be, but Math still encompasses all Math so there’s no need to pluralize it.
The discipline is “mathematics.” It’s really not unreasonable that in some parts of the world, it got shortened to maths.
And the other error present is the incorrect pluralisation. Mathematica means the entire area or domain of knowledge, while mathematics sounds like several lines of thinking, which is weird when we use it as a singular. Maths doesn’t refer to several kinds of math, and that’s confusing.
And British English is wrong. Those motherfuckers stick “u” into way too many words.
Anymore of this disrespect and I’ll stick “u” into an early grave.

I feel obligated to say English that comes from England is the only real English. You can keep your Americanese.
