Operator Precedence In the following list, operators on the same line are of equal precedence. As you move down the list, each line is of lower precedence. When the order of operations is not dictated by parenthe- ses, the operator of higher precedence executes before an operator of lower precedence. When operators have equal precedence, binary operators execute in left-to-right order, and unary oper- ators execute in right-to-left order.
