Answer:

(6 - 6 - 9 - 3 - 2 + 2 + 4 +2 + 5 - 5) / 10

Step-by-step explanation:

The mean is adding up all the numbers then divide it by that many numbers.  There are 10 numbers total.  

Since some are negative you subtract those.  basically 6 + (-2) is the same as 6 - 2.

6 - 6 - 9 - 3 - 2 + 2 + 4 +2 + 5 - 5

ow find that and divide by 10
