Changing Evaluation Order of Operators

Go Up to Determining Precedence of Operators

To change the evaluation order of operations in an expression, use parentheses to group operations that should be evaluated as a unit, or that should derive a single value for use in other operations. For example, without parenthetical grouping, 3 + 2 * 6 evaluates to 15. To cause the addition to be performed before the multiplication, use parentheses:

(3 + 2) * 6 = 30

Tip: Always use parentheses to group operations in complex expressions, even when default order of evaluation is desired. Explicitly grouped expressions are easier to understand and debug.
