 \section{Notations}
 
+\Question{How can I define a notation for square ?}
+
+You can use for instance :
+\begin{verbatim}
+Notation "x ^2" := (Rmult x x) (at level 20).
+\end{verbatim}
+Note that you can not use :
+\begin{verbatim}
+Notation "x ²" := (Rmult x x) (at level 20).
+\end{verbatim}
+because ``²'' is an iso-latin character. If you really want this kind of notation you should use UTF-8.
