The different parts of a rule expression are evaluated in a specific
order. In particular each operator has a certain priority, so that they
are always evaluated in the same order. Functions and the unary operators
'-' and 'Not' are evaluated first followed by the binary operators. The
priority relationship for the binary operators is set out in the table below
with the first operator to be evaluated listed first.
