Answer 1

a) 2 × 3 × (-6) + 3 × (-1) × 1 + (-4) × 2 × 3

-2 × 3 × 6 - 3 × 1 × 1 - 4 × 2 × 3

-6 × 6 - 3 - 8 × 3

-36 - 3 - 24

-63

b) 1 × 0 × (-5) + (-3) × (-1) × 8 + (-5) × 5 × 3

0 + 24 - 75

-51

c) 5 × 2 × (-4) + 6 × 3 × (-1) - [6 × (-3) × 5]

-40 - 18 - [-90]

-40 - 18 + 90

32

d) 2×0×3+(-3)×5×4+(6×3×2+3×2×1×(-2)×5×2)

0 - 60 + (36 - 120)

-60 + (-84)

-60 - 84

-144

e) 3 × 2 × 1 × 0 - (3 × 2 × 5 - 4)

0 - (30 - 4)
