This operator adds values on either side of the operator. 4 - (Subtraction) This operator subtracts right-hand operand from left-hand operand. 5 - (Unary minus) This operator is used to change the sign of the operand. 6 / (Division) This operator divides left-hand operand by right...
When there is more than one arithmetic operator in an expression, multiplication and division are calculated first, followed by subtraction and addition. When all the arithmetic operators in an expression have the same level of precedence, the order of execution is left to right. ...
