\begin{equation}
math formula
\label{eqno1}
\end{equation}
</pre>
The equation environment centers your equation on the page and places
the equation number in the right margin.
<p>
The <a href="ltx-252.html"><tt>\label</tt></a> command is required
only if you want to use a <a href="ltx-303.html"><tt>\ref</tt></a>
command to refer to the number assigned to this equation.
<p>
The <a href="ltx-421.html">Display Math</a> environment gives the
same effect without the equation number.
