a) (-32) . 43 + (-32) . 65 - (-32) . 8
= (-32) . (43 + 65 - 8)
= (-32) . 100
= -3200
b) (-43) . 25 + 25 . (-19) + 25 . (-38)
= 25 . [(-43) + (-19) + (-38)]

= -2500
c) (-26) . 13 + 86 . (-26) + (-26)
= (-26) . (13 + 86 + 1)
= (-26) . 100

d) (-17) . 39 + (-17) + (-17) . 60
= (-17) . (1 + 39 + 60)
= (-17) . 100
