Hierarchy
of
Operators
When your expressions have multiple operators, BASIC performs the
operations according to a well-defined hierarchy so that results are
always predictable.
Parentheses
When a complex expression includes parentheses, BASIC always
evaluates the expressions inside the parentheses before evaluating
the rest of the expression. For example, the expression:
8 -
(3
- 2)
is evaluated like this:
3 - 2
= 1
8 - 1
= 7
2-45
