Using the following notation:

$$math$$

to insert displaymath environments in latex is desirable. This is better
when more than one line of math is required, since we would otherwise need
a hanging initial $$math.

Using \begin{displaymath}\end{displaymath} is possible, but not as convenient.

The symbols $$ are very unlikely to mean "dollar dollar" when alone at the
beginning of a line.
