Find the values of the following expressions: (a) (−5) × (18 + (−3)) (b) (−7) × 4 × (−1) (c) (−2) × (−1) × (−5) × (−3)

(a)
Answer

−75

(b)
Answer

28

(c)
Answer

30

Explanation

(a) First simplify inside brackets: 18 + (−3) = 15. Then (−5) × 15 = −75. (b) Two negative factors (even number) → positive product. 7×47 \times 4 × 1 = 28. (c) Four negative factors (even number) → positive product. 2×12 \times 1 × 5×35 \times 3 = 30.
