Answer: -4 and 8
Step-by-step explanation: For getting from 2, and adding 6, it would get you to 8. Now remember, no matter what order you put the numbers in addition, the answer is always the same. To get 6 units back from 6, try this. Subtract 2 from 6 (6 - 2). Your answer should be 4 correct? Now, if it were to go backwards, what would it be, -4. Great job! A good listener you are. Hope this helped! :)
