Some operators will have higher precedence than others. For example, multiplication operator will have higher precedence than addition operator. For example a = 2 + 3 * 5; here, a will be assigned 17, not 25 because operator * has higher precedence than +, so 3*5 gets multiplied first and then 2 gets added to the multiplication result of 3*5. In the table below, operators with the highest precedence appear at the top of the table and operators with the lowest precedence appear at the bottom. In the expression, higher precedence operators will be evaluated first.
