Full Answer

  1. Verify signs

    The number should be preceded by a minus/negative sign (-). Positive numbers do not have a sign.

  2. Check operator

    The operator has to be a minus symbol (-) between the number values.

  3. Complete the calculation

    The operator and sign of the second number then become positive. For example, -3 - (-3) = -3 + 3 = 0 and 3 - (-3) = 3 + 3 = 6.
