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: 8 - (-4) = 8 + 4 = 12
  • If both signs are negative, the answer will be negative.
    Example: -8 - (+4) = -8 - 4 = -12
  • 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: 6 - (+2) = 6 - 2 = 4
    Example: -6 - (-2) = -6 + 2 = -4
    Example: 6 - (-2) = 6 + 2 = 8
    Example: -6 - (+2) = -6 - 2 = -8
