Answer

Maths / Math = Mathematics, and it is a subject) Its form is Singular, same as Phonetics, for instance, as far as I remember) That is why when you say "maths" or "math" you should put "is", not "are" :)

Answer

In American English math is singular, so, "when when your math is done..."
I think, though I am not sure, that in British English "maths" should be treated as plural.  I'm interested in hearing what our UK friends have to say about this.

Answer

There's no plural for any subject u study even though they are singular & find s in the endings like maths, physics, civics, economics. So always to be used as "is".
 Eg; Maths is too hard to understand the formula.
