Merriam-Webster online is not very helpful. It gives math as an abbreviation of mathematics (first usage circa 1847), the lattter 'noun plural but usually singular in construction'.
I'm not sure if a longer entry may be available, as these definitions appear as 'definition for English learners'. So just my two bits, as they say.
