How to Subtract Negative Numbers?

To subtract negative numbers, you need to remember a few rules. For example, +5 – (-6) = +5 + 6= +11. You get this answer because the rule is that when two negative signs follow each other, as in the example, they become a plus sign. In other words, subtracting a negative 6 from a positive 5 gives us a positive 11. You can find more information here:
