Operator precedence determines how operators are parsed concerning each other. Operators with higher precedence become the operands of operators with lower precedence. Consider an expression describable by the representation below. If OP 1 and OP 2 have different precedence levels see the table below , the operator with the highest precedence goes first and associativity does not matter.
