Adding Signed Numbers

December 15, 2020 by Veerendra

Adding Signed Numbers

Rules for Adding:

  1. When you add two numbers with the same signs,
    1. add the absolute values, and
    2. write the sum (the answer) with the sign of the numbers.
      Examples:
      (+5) + (+7) = +12
      (-6) + (-8) = -14
      (9) + (5) = 14
  2. When you add two numbers with different signs,
    1. subtract the absolute values, and
    2. write the difference (the answer) with the sign of the number having the larger absolute value.
      Examples:
      (+7) + (-9) = -2
      (-12) + (+15) = +3
      (-20) + 14 = -6
