  • (+12)-(+2) = 12 - 2 = 10
    (+24)-(-4) = 24 + 4 = 28
    (-8)-(+18) = - 8 - 18 = 26
    (-11)-(-13) = - 11 + 13 = 2
    (-17)-(-13) = - 17 + 13 = - 4
    (+13)-(+7) = 13 - 7 = 6
  • (+12)-(+2) = 12 - 2 = 10
    (+24)-(-4) = 24 + 4 = 28
    (-8)-(+18) = -8 - 18 = -26
    (-11)-(-13) = -11 + 13 = 2
    (-17)-(-13) = -17 + 13 = -4
    (+13)-(+7)  = 13 - 7 = 6
