I recently acquired a copy of mathematica after a term of using it over a network in Calc III, but I am unable to use it to do the same functions as before. The number one problem is, that there is no input box when I try to plot, compute, etc. The only thing that is available is text and that is definitely not what I tend to use Mathematica for. Can someone provide me some insight into how to make the standard blue box and inputs--I'm using version 7.0 . Thanks in advance!
