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?
