I enjoy learning things and then working on my own personal studies. I'm loving calculus right now and am working with it as much as possible in between my other classes. The problem I have set out for myself right now is to find a limit that represents ∏. Before I go on can someone please explain to me how to use the math font? When I try to use it all I get is a bunch of words and symbols I don't know how to use it. Thanks.
