# Equivalent of LaTeX “eqnarray” in Microsoft Word 2007 equation editor?

In LaTeX one can use the eqnarray environment to display a set of equations aligned horizontally on their equality signs or other element, e.g.:

\begin{eqnarray*}
x &=& 5! \\
&=& 5 \cdot 4 \cdot 3 \cdot 2 \cdot 1
\end{eqnarray*}


This will render as follows (notice the alignment of the equality signs):

Is there a good way to achieve the same effect in Microsoft Word 2007's built in equation editor?
