Where is the Tool Box?

  1. Jul 18, 2012 #1
    I want to display complex equations. It was suggested to me that I click on the sigma icon in the Toolbox. However, I can't find the Toolbox.
    I see the quick symbols box. However, underneath there is a suggestion to look for the sigma icon. I don't see a sigma even in the quick symbols box.
    I don't have a LaTex word processor.
    Does the forum provide a LaTex editor?
