  • a. -8x(-32+17) =
    -8x(-15) =
    -120.

    b. [-12-(-30)] x (-21) =
    18x (-21) =
    -378

    c. 9 x (-4x5) x (10-14) =
    9 x (-20) x (-4) =
    -180 x (-4) =
    720.

    d. (-15+7) x 50 x [5 x (-12)] =
    -8 x 50 x (-60) =
    -400 x (-60) =
    24.000

    e. [14 x (-7)] + [-19 x (-8)] =
    -98+152 =
    54

    f. -8-[-4 x 15] + [11 x (-7)] =
    -8-60+(-77) =
    -145
