Perhaps you mean “the math”? That is an American colloquialism used to refer to one calculation or small set of calculations. But we are talking about “math”, not “the math”. Again, “math” is short for mathematics. It is already plural.
Attempting to pluralize something that is already in its plural form is nonsensical. Do they not teach your “childrens”, which is what I assume you call them, that in school?
