**Ms. Sue**, Tuesday, September 27, 2011 at 8:15pmThanks. Now I can see the numbers more clearly.

1)

-6

3

-2

6

7

-3

-5

8

Positive numbers: 3 + 6 + 7 + 8 = 24

Negative numbers: -6 -2 - 3 - 5 = -16

24 - 16 = 8

8/8 = 1

Try number 2.

**Marko**, Tuesday, September 27, 2011 at 8:35pmi got

32+0+52 + 12 = 96

-17 + -9 + -14 = -40

96 - 40 = 56

56 /8 = 7 as the mean
