    Calcule.

    K= 5 + 13 - 4 + 3 - 6

    K = 5 + 13 + 3 - 4 - 6

    K = 21 - 10

    K = 11

    L = - 7 + 5 - 4 - 8 + 13

    L = -7 - 4 - 8 + 5 + 13

    L = -19 + 18

    L = -1

    M = - 8 + 5 – 4 + 3 + 4

    M = -8 + 5 + 3 - 4 + 4

    M = -8 + 8

    M = 0

    N = - 17 + 24 – 18 – 18 + 19

    N = -17 - 18 - 18 + 24 + 19

    N = -53 + 43

    N = -10

    P = 12 – 17 – 13 + 9 + 7

    P = 12 + 9 + 7 - 17 - 13

    P = 28 - 30

    P = -2
