    Yup, that's the one. How on earth do you- oh is that on the "equation" tab at the bottom? Ahhaha... I'm slow. Yes that's what I mean.

    But anyways, \[\large +(-x)~=~-x\] so \[\large +(-\frac{3}{8})~=~-\frac{3}{8}\] and btw, if you want to learn latex check out http://openstudy.com/study#/groups/LaTeX%20Practicing!%20%3A)

    What I'm trying to say is \[\large (\frac{7}{3}~+~(-\frac{3}{8}))~=~(\frac{7}{3}~-~\frac{3}{8})\]

    So the next step is to get the a common denominator. Know how to do that?

    Oh yeah, I can do that. But with this problem it's kinda difficult for me and I don't know how to apply it.
