    Thanks. 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.

    i got
    32+0+52 + 12 = 96
    -17 + -9 + -14 = -40
    96 - 40 = 56
    56 /8 = 7 as the mean
