\section{Numbered Equations\protect\vspace{1pt}}

You can number a displayed equation by adding a label to your displayed
mathematics. The label appears in a small box to the side of the display:

\begin{equation}
a^{2}+b^{2}=c^{2}  \tag{Eqn. 1}
\end{equation}

You can also add a name to the label, which appears in print:

\begin{equation}
a^{2}+b^{2}=c^{2}  \tag{Eqn. 1}  \label{Pythagoras}
\end{equation}

You can jump to a label with a name using a \hyperref{hypertext link}{}{}{%
Multiline_links.tex} from another location.

If you want to jump to a display but you don't want a name for the display
to appear in print, enter a \hyperref{marker}{}{}{Markers.tex} for the
display.

\subsubsection{\noindent $\blacktriangleright $\quad \textbf{To } number
displayed mathematics}

\begin{enumerate}
\item  Select the display to be numbered.

\item  Click\FRAME{itbpF}{19.5625pt}{18.8125pt}{2pt}{}{}{property.wmf}{%
\special{language "Scientific Word";type "GRAPHIC";display "PICT";valid_file

"1";cropbottom "0";filename 'property.wmf';file-properties "XNPEU";}}, or
from the Edit menu, choose Properties.

\item  If the display is a \hyperref{multiline display}{}{}{%
Multiline_displays.tex}, choose the line you want to number.

\item  Choose Custom.

\item  If you want to link to the line from another location, enter a name
in the Key for this Line box.

\item  In the entry area, type the number for the line.

\item  If you want to align the numbers for a multiline display:

\begin{enumerate}
\item  Choose Advanced.

\item  Check Enable Alignment.

\item  Choose the alignment you want.
\end{enumerate}
\end{enumerate}

On the screen, the line number appears in a gray box. If you gave the line a
key, the box also contains the key name.

\subsubsection{\noindent $\blacktriangleright $\quad \textbf{To }remove a
number from displayed mathematics}

\begin{enumerate}
\item  Select the display.

\item  Choose Properties.

\item  Choose the line you don't want to label.

\item  Choose None.

\item  Choose OK.\medskip
