Operator precedence

An expression is evaluated in the order determined by operator precedence, and precedence is meaningful only if the expression includes multiple operators. The higher precedence operator is evaluated first. Operand grouping can be enforced by using parentheses.

Associativity rules are applied to the order of operation for operators that have the same precedence.

Precedence order, from highest to lowest, and associative are listed here:
