LaTex homework assignment - What's wrong?

Hello! For one of my classes, I was assigned to form a 2-paged work in Latex. This work refers to the title page with introductory information while the 2nd page refers to 5 valuable equations. Now, I've never learned LaTex until just now and it was basically my first programming experience. Even then, I did not fully comprehend the LaTex system.

Anyways, is there anything systemically wrong with the following code? It won't compile for some reason.

\usepackage{amssymb}

\linespread{1.3}

\usepackage{fullpage}

\textwidth=14cm

\textheight=20.6cm
