I wish to recreate the following vertical addition using the equation editor in Microsoft Word 2013:

I have tried using an empty 3x3 matrix and filling it with the relevant symbols, however I cannot draw the horizontal line in-between the problem and the solution.

I have also tried using separate equations and an underbar accent. However this is a less-than-ideal solution due to the space characters used for horizontal spacing. ^{(*shudder*)}

**Is there a way I can elegantly reproduce vertical addition using the MS Word 2013 equation editor?**
