## equation

\begin{equation}
math formula
\label{eqno1}
\end{equation}

The equation environment centers your equation on the page
and places the equation number in the right margin.

The `\label` command is
required only if you want to use a
`\ref` command to refer to the
number assigned to this equation.

The Display Math environment gives
the same effect without the equation number.
