\begin{solution} ... \end{solution}
tags. One can show/hide these by putting this in the preamble:
\usepackage{ifthen}
%Set this boolean to true or false to display solutions
\newboolean{issolutions}
\setboolean{issolutions}{false}
\ifthenelse{\boolean{issolutions}}{\newenvironment{solution}{}{}}{\excludecomment{solution}}
Then set ``issolutions'' to true or false as needed to show/hide the solutions.
