  1.    63+|-128 
    =63-128
    = -65
    b) (-125)+45 
    = -125+45 
    = -80
    c)(-15)+|-45|+15 
      = -15 -45+15
    = -15+15-45
    = 0-45
    = -45

  2. Answer
    63 + |-128| = 63 + 128 = 191
    (-125) + 45 = -125 + 45 = 45 – 125 = -80
    (-15) + |-45| + 15 = -15 + 45 + 15 = (15 – 15) + 45 = 0 + 45 = 45
