Answer 1

1. b + c = 5 + 4 = 9
              = 6 -3 = 3
             = -7 + 2 = -5
             = -8 -1 = -9
             = 9 + 0 = 9
 a x (b + c) = 1(9) = 9
                   = -2(3) = -6
                   = 3(-5) = -15
                  = -4(-9) = 36
                  = 5(9) = 45
a x b = 1 x 5 = 5
         = -2 x 6 = -12
          = 3 x -7 = -21
          = -4 x -8 = 32
          = 5 x 9 = 45
a x c = 1 x 4 = 4
          = -2 x -3 = 6
          =  3 x 2 = 6
          = -4 x -1 =4
          = 5 x 0 = 0
(a x b) + (a x c) = 5 x 4 = 20
                           = -12 x 6 = -72
                           =-21 x 6 = -126
                          = 32 x 4 = 128
                          = 45 x 0 = 0
