  • Bonjour,

    A = 20 - (1 + 5 x 3)

    A = 20 - (1 + 15)

    A = 20 - 16

    A = 4

    B = 24 - 4 x 4 + 2

    B = 24 - 16 + 2

    B = 10

    C = 5 + 5 x (6 + 3)

    C = 5 + 5 x 9

    C = 5 + 45

    C = 50

    D = 16 - 7 x 2 - 1

    D = 16 - 14 - 1

    D = 1

    E = (50 - 6 x 8 + 4) x 5 + 4

    E = (50 - 48 + 4) x 5 + 4

    E = 6 x 5 + 4

    E = 30 + 4

    E = 34

    F = 3 + (4 + 4) x 8

    F = 3 + 8 x 8

    F = 3 + 64

    F = 67

    G = 45 - 5 x 6 + 8 x 3

    G = 45 - 30 + 24

    G = 39

    H = 9 + 4 x 8 + 1

    H = 9 + 32 + 1

    H = 42

    I = 2 x [14 - 6 x (7 - 5)]

    I = 2 x (14 - 6 x 2)

    I = 2 x (14 - 12)

    I = 2 x 2

    I = 4.
