\begin{document} % This is where the document starts.

The text is automatically formatted in a \LaTeX~ document.  Spaces
between                 words mean nothing to \LaTeX.  Nor does
one return.  % \LaTeX makes a fancy LaTeX logo.

Two returns gives a new paragraph.  

\section{Math is easy in \LaTeX} % This puts a section number and 
				 % section title.

\[ y=mx+b \] % this is a simple equation  \[ starts centered math mode
	     % \] ends centered math mode.

You can also insert math directly into the text.  For example, the
point-intercept form of a line is $y=mx+b$.  % text between $ $ is
					     % math mode.

\end{document}  % This is the end of the document
