 \begin{example}\label{ex:quotient-is-weight-mod}
   Given a weight module \(M\), a submodule \(N \subset M\) and \(\lambda \in
-  \mathfrak{h}^*\), it is clear that \(= \mfrac{M_\lambda}{N} \subset
+  \mathfrak{h}^*\), it is clear that \(\mfrac{M_\lambda}{N} \subset
   \left(\mfrac{M}{N}\right)_\lambda\). In addition, \(\mfrac{M}{N} =
   \bigoplus_{\lambda \in \mathfrak{h}^*} \mfrac{M_\lambda}{N}\). Hence
   \(\mfrac{M}{N}\) is weight \(\mathfrak{g}\)-module with
