Example
  • Positive Number + Positive = Positive Number
  • 7 + 4 = 11
    2 + 15 = 17
  • Negative Number + Negative Number = Negative Number
  • -4 + (-9) = -(4 + 9) = -13
    12 + (-43) = -(12 + 43) = -31

  • Positive + Negative OR Negative + Positive

    case 1: The positive number is larger: Answer = Positive

    case 2: The negative number is larger: Answer = Negative

  • case 1:
