Best ResponseYou've already chosen the best response.1No, most people make it: \[ \oint\oint \]There's no standard LaTeX way to do it, you need a package called wasysym, that makes it: \oiint

Best ResponseYou've already chosen the best response.2How can I invoke packages here? I tried using \usepackage{wasysym}, but it does not work.

Best ResponseYou've already chosen the best response.1No, you cannot do it on here, since I don't think the \(\LaTeX\) compiler parses it.

Best ResponseYou've already chosen the best response.1Simply do something like: \[ \underbrace{\oint\oint}_\textrm{Surface} \]\underbrace{\oint\oint}_\textrm{Surface} You're kind of limited in this case... but you could add this to the Feedback Page.
