When an expression contains multiple binary operators, the precedence of the operators controls the order in which the individual binary operators are evaluated. For example, in the expression x + y * z is evaluated as x + (y * z) because the * operator has higher precedence than the + operator. The following table lists the binary operators in descending order of precedence:

When an expression contains two operators with the same precedence, the associativity of the operators controls the order in which the operations are performed. All binary operators are left-associative, meaning that operations are performed from left to right. Precedence and associativity can be controlled using parenthetical expressions.
