Subtracting Negative and Positive Integers

To subtract integers, change the sign on the integer that is to be subtracted.

  • If both signs are positive, the answer will be positive.
    Example: 14 - (-6) = 14 + 6 = 20
  • If both signs are negative, the answer will be negative.
    Example: -14 - (+6) = -14 - 6 = -20
  • If the signs are different subtract the smaller absolute value from the larger absolute value. The sign will be the sign of the integer that produced the larger absolute value.
    Example: 14 - (+6) = 14 - 6 = 8
    Example: -14 - (-6) = -14 + 6 = -8
