Aargh. If the phrasing gets you then you _do_ _not_ know the definition!

If you can't state the definition coherently, which indeed you can't, then no, your understanding is not good enough to be able to write proofs.
Really. A feel to nice for how. To get it, so if you have to ride then to it, otherwise. So wit unless rain time less.
(What, you didn't follow that last paragraph? I was trying to say "it's a nice day here in Oklahoma". I know what I meant, it's the phrasing that always gets me...)

Math _is_ _very_ different in this regard. I certainly warn my students of this, rarely helps. Your professors are just assuming that you _realize_ that you need to know what the words mean...
