Math Formulae
=============

   There are three environments that put LaTeX in math mode:
     For Formulae that appear right in the text.

     For Formulae that appear on their own line.

     The same as the displaymath environment except that it adds an
     equation number in the right margin.

   The math environment can be used in both paragraph and LR mode, but
the displaymath and equation environments can be used only in paragraph
mode.  The math and displaymath environments are used so often that
they have the following short forms:
         \(...\)     instead of     \begin{math}...\end{math}
     
         \[...\]     instead of     \begin{displaymath}...\end{displaymath}

   In fact, the math environment is so common that it has an even
shorter form:
         $ ... $     instead of     \(...\)
