It may not be necessary for preview, but it seems to be necessary for
export: no element of org-export-latex-classes includes
\usepackage{amsmath} and when I process the LaTeX file, I get errors
without it:

(./waterloo.out) (./waterloo.toc)
! Misplaced alignment tab character &.
l.28 1&
       d\\
! Misplaced alignment tab character &.
l.29 d&
       d\\
[1] (./waterloo.aux) )
(see the transcript file for additional information)

Thanks,
