No. Mathematics is singular. It describes a thing—a field of study—not many things. The S on the end doesn't indicate plurality.its Maths, short for Mathematics, Math would be short for Mathematic. which isn't a thing.
Mathematics is a mass noun and usually takes a singular verb. You don't say mathematics 'are' my favorite subject.. You say "mathematics IS my favorite subject."
So when you shorten the noun, it's redundant to add the 's'.
That said, it's a preference thing. Americans and Canadians have the common sense to not add the 's' at the end since the whole point is to abbreviate... The English on the other hand do add it.. But it's just a preference. It's neither logical nor more correct.
