  • 1. -25+30= 5
    2. -67+(-33)
    = -67 - 33
    = -100
    3. 129+(-50)
    = 129 - 50
    = 79
    4. -250+125= -125
    5.300+(-175)
    = 300 - 175
    = 125
    6. -450+(-150)
    = -450 - 150
    = -600
    7. -70-55= -125
    8. -120-(-70)
    = -120 + 70
    = -50
    9. 200-(-75)
    = 200 + 75
    = 275
    10. -245-125= -370
    11. -400-(-150)
    = -400 + 150
    = -250
  • 1. -25+30 = 5
    2. -67+(-33) = -67-33 = -100
    3. 129+(-50) = 129-50 = 79
    4. -250+125 = -125
    5. 300+(-175) = 300-175 = 125
    6. -450+(-150) = -450-150 = -600
    7. -70-55 = -125
    8. -120-(-70) = -120+70 = -50
    9. 200-(-75) = 275
    10. -245-125 = -370
    11. -400-(-150) = -400+150 = -250
