Hi,

How can I use this package. I tried with \newcommand but it displayes
exactly what is in command definition but not calculation result :

\usepackage{calc}
\newcommand{\aaa}{4 - 5}
\begin{document}
\aaa
\end{document}

=> output : 4 - 5

And smone tell me that calc package doesn't work with real number. It's
right?

Thank you in advance
