\section{Empty Brackets}

When you need a single expanding bracket, such as to contain a set of
equations, you complete the pair of brackets with an empty bracket. Empty
brackets do not appear in print, but they are shown on the screen as
vertical dotted lines, like this:\FRAME{itbpF}{13.0625pt}{22.4375pt}{5pt}{}{%
}{empty.wmf}{\special{language "Scientific Word";type "GRAPHIC";display
"PICT";valid_file "F";width 13.0625pt;height 22.4375pt;depth
5pt;original-width 11.3125pt;original-height 20.3125pt;cropleft "0";croptop
"1";cropright "1";cropbottom "0";filename 'empty.wmf';file-properties
"XNPEU";}}.

\subsubsection{$\blacktriangleright $\quad To enter an empty left or right
bracket}

\begin{enumerate}
\item  Click\FRAME{itbpF}{22.4375pt}{21.0625pt}{2pt}{}{}{brackets1.wmf}{%
\special{language "Scientific Word";type "GRAPHIC";maintain-aspect-ratio
TRUE;display "PICT";valid_file "F";width 22.4375pt;height 21.0625pt;depth

\item  If you want an empty left bracket, locate the empty bracket\FRAME{%
