Rules for integer operation 1.The sum of two positive integers will always be positive, to get the answer you add. 2.The sum of two negative integers will always be negative, to get the answer you add. 3.The sum of two integers with different signs will have the sign of the larger number, to get the answer you subtract. 4.To subtract two integers, change the subtraction to addition and change the sign of the number to its opposite. Ex. (add a line, change the sign) 5.The product of two integers with the same sign will always be positive, to get the answer you multiply. 6.The product of two different signs will always be negative, to get the answer multiply. 7. The quotient of two integers with the same signs will always be positive, to get the answer you divide. 8.The quotient of two integers with different signs will be negative, to get the answer you divide.
