let the two numbers are -4 and -9

remember rule 

1) + - = -

2) - - = +

addition=-4+(-9)

            = -4 - 9

            = -13   [sign is negative because 9 is greater and is having - sign]

subtraction = -4 - (-9)

                   = -4 + 9

                  = 5 [sign is positive because 9 is greater and is having - sign]

subtraction= -9 - (-4)

                 = -9 +4

                 = -5
