I downloaded WinEdt, MiKTeX with TeXworks, and SumatraPDF for viewing.
I was alerted that WinEdt is shareware and I will have to pay in one month to keep it. Is this the case with the other two programs as well?
I am not going to need anything fancy, I want the absolute minimal requirements that optimally won't involve buying anything to create math PDFs written in LaTeX.
Can I just write directly in TeXworks and avoid using an editor at all? That would be fine. I just want to be able to make PDFs on my home computer if I don't have internet, so I don't have to use online resources such as writelatex.com (and I don't feel that's an appropriate use of those websites anyway, if I'm not collaborating).
