For more than a century, mathematics became another form of plural mathematics. The English abbreviation is essentially a reduplicated plural which in my mind is redundant and doesn’t make much sense considering how both the English and Americans use it (that is, “math is fun, maths is fun” and not “math are fun, maths are fun”).

Does the abbreviation have a verbal agreement and should be used with a singular verb as opposed to a reduplicated plural?
