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