Well, OK, thanks anyway, but this is Lamport-style, standard LaTeX. One of
the aims of the AMS package, though, is to provide resources that render
mathematical display that is aesthetically more appealing than standard
LaTeX...
Just for you to notice the difference between array and subarray environments
in this case, I'm attaching a small .tex file which compares both instances.
Cheers.
