a) 12 x [9 + (-2)] = [12 x 9] + [12 x (-2)]

= 12 x (9-2) = (108) + (-24)

= 12 x (7)= 108 - 24

= 84 = 84

Hence verified

b) (-8) x [10 + (-3)] = [(-8) x 10] + [(-8) x (-3)]

= (-8) x [10-3] = (-80) + (24)

= (-8) x 7 = (-80) + 24

= (-56) = (-56)

Hence verified

c) (-15) x [(-38) + 5] = [(-15) x (-38)]
+ [(-15) x 5)

= (-15) x (-33) = (570) + (-75)

= 495 = 495

Hence verified

d) (-6) x [ (-15) + (-8)] = [(-6) x (-15)] +
[(-6) x (-8)]

= (-6) x [ (-15) - 8] = (90) + (48)

= (-6) x (-23) = 138

= 138 = 138

Hence verified
