The same concept is applied when taking away a positive number from a negative number. Now imagine taking away 2 from 5, what would you do? You would take two steps to the left from five, and that would make your answer 3. This is because you are actually adding the numbers on the negative side of the number line. When subtracting a positive number from a negative number, the difference will always have a negative sign.
