    A = (-7) x (-2) + (-54) : (+6)

    A = 14 - 9

    A = 5


    B = -8(-3 - 4) - (-5)

    B = -8 x -7 + 5

    B = 56 + 5

    B = 61


    C = 72 : (-9) - (-15 + 7)(-20 + 13)

    C = -8 - (-8) x -7

    C = -8 - 56

    C = -64


    D = -10[-48 + 4(12 - 4 x 5)] + 510

    D = -10(-48 + 4(12 - 20)) + 510

    D = -10(-48 + 4 x -8) + 510

    D = -10(-48 - 32) + 510

    D = -10 x -80 + 510

    D = 800 + 510

    D = 1310


    E = (17 - 5)/(10 - 14)

    E = 12/(-4)

    E = -3


    F = (51 - 3 x 7)/(6 x 4 - 5 x 6) - 12

    F = (51 - 21) / (24 - 30) - 12

    F = 30/(-6) - 12

    F = -5 - 12

    F = -17
