Can I remove the vertical space in the first column?

Using the alignat* environment from »amsmath« might be the better option. – Thorsten Donig Sep 27 '13 at 16:40
@ThorstenDonig That's definitely a better solution, but I am curious as to why the problem exists to begin with. – Sean Allred Sep 27 '13 at 17:00

It isn't actually vertical space it is a horizontal box of paragraph text. You always get this if you start a paragraph with display math (which is why you should never do it). If you start display math in vertical mode TeX recovers by starting a paragraph then inserting the paragraph indentation box and horizontal \parfillskip glue then breaking the partial paragraph.

What this means is that you can do


To avoid the problem, but really you shouldn't be in the situation anyway.
