    $\begingroup$ I think the OP means to ask something like what follows. Take an arbitrary question and assume (multivariable-calculus) is one of its tags. Pick the correct answer: i) (calculus) tag should be added; ii) (calculus) tag should not be added. $\endgroup$ – Git Gud Jun 27 '14 at 18:45

I see two possible questions here.

Q1: Why have tags and instead of and ?

A1: When students take a single-variable calculus course, they do not think of it as single-variable calculus. It is just calculus to them. Only later they may (or may not) get the appreciation of the multivariable calculus as a somewhat different subject. Depending on whether they do that, they will tag questions as or as .

Q2: If a question is tagged , should it also be tagged ?

A2: It can be, but this is not necessary. Most are not tagged (we have $4509$ questions with multivariable tag only, versus $1211$ with both tags). Given the large number of questions, one can be reasonably confident that users interested in following this tag have added it to their favorites, along with (or instead of ) .
