Explanation:

Step1: Define the scores

Let wins be positive and losses be negative. So the scores are 9, -18, 7, 10, -2, 6.

Step2: Calculate the sum

$9+( - 18)+7 + 10+( - 2)+6=(9 + 7+10 + 6)+(-18 - 2)=32-20 = 12$.

Step3: Calculate the mean

The mean is the sum divided by the number of games. There are 6 games. So the mean is $\frac{12}{6}=2$.
