The command is \oiint, but julien doesn't have wasysym turned on so it doesn't work here. I'm not sure how to fake it; {\huge\circ} gives a decent loop but I can't get the forum to allow enough negative space to merge that with two \int symbols or an \iint symbol.

Right, that's the sort of solution I suggested when I talked about negative spacing above. But I couldn't get it to work here -- there seems to be a limit as to how much negative space can be used.

I am glad I learned LaTeX. I was originally "forced" to use it because I felt so guilty about posting expressions in barely readable form like I would enter in a calculator or something, but now I can even create cool-looking documents with the LaTeX software and pretend to be a mathematician presenting some research and I feel really cool being able to show work in LaTeX because my handwriting is very ugly.

I started trying to help other people with maths and I realized how annoying it could be trying to read fractions and expressions with missing parentheses
