\section*{Some Simple Math Examples}

Mathematical text is most easily entered in one of two ways. The first
is to place the text within backslash-square brackets, as follows:

\[\forall x @ x > 2 \]

or

\[ \{ 1,2 \} \subseteq \{ 1,2,3 \} \]


The other way is to place the mathematical text between dollar signs,
in which case it will appear in-line.  For example the formula $x + y
> 3$ would appear within the running text.
