  1. Answer:

    a)280

    d) 0

    8) -48

    b) -168

    e) -960

    c) -1080

    g) -1700

    Step-by-step explanation:

    a) -7×-4×10

    =28×10

    =280

    d) 21×-5×9890×0

    =0

    8) (-5+4)×48

    = -1×48

    = -48

    b) -2×14×-6×-1

    = -28×6

    = -168

    e) (8)(-5)×(-6)×4

    = -40×-24

    = -960

    c) (-18)×(-10)×(-2)×3

    = 180×-6

    =-1080

    g) (-12-5)×100

    = -17×100

    = -1700
