The sum will be the result of adding numbers, while the difference will be the result of subtracting them. For instance, in the math problem 4 + 3 – 5, the sum of 4 and 3 will be 7, and the difference between 7 and 5 will be 2. In this example, 2 is the final answer to the math problem.

Rule 3: Subtracting a negative number from a negative number – a minus sign followed by a negative sign, turns the two signs into a plus sign.
