Question

a)8.(-6).(-7)


b)12 . 4/(-2)


c)[(-225)/15]-(-85)

d)(-4).[(-6)/2]

e)[(-13.14).(20/10)]

f)[(5.8)/(2.10)].[(18/(-6)]


g){[(-16).(-16)]/(-8).(-8)}

Answer 1

a) 8(-6x-7) = 8(56) = 448

b) 12x4/(-2) = 48/-2 = -24

c) [(-225)/15] - (-85)

[-15] + 85 = -15 + 85 = 70

d) (-4).[(-6)/2]


(-4).[-3] = -4 x -3 = 12

e)  [(-13x14).(20/10)]

[(-182).(2)] = -182 x 2 = -364


f)  [(5x8)/(2x10)]*[18/(-6)]

[(40)/(20)]*[(-3)]

[2]*[-3] = 2 x -3 = -6

g) {[(-16)x(-16)]/(-8)x(-8)}

{[256]/(-8)x(-8)}

{(256/-8)x(-8)}

{(32)x(-8)} = 32 x -8 = -256
