Answer key · Multiply and divide integers
- 1.-16 — A negative times a negative is positive; unlike signs give a negative. (−4) × 4 = -16.
- 2.7 — A negative times a negative is positive; unlike signs give a negative. (−1) × (−7) = 7.
- 3.49 — A negative times a negative is positive; unlike signs give a negative. 7 × 7 = 49.
- 4.-96 — A negative times a negative is positive; unlike signs give a negative. 12 × (−8) = -96.
- 5.18 — A negative times a negative is positive; unlike signs give a negative. 9 × 2 = 18.
- 6.-18 — A negative times a negative is positive; unlike signs give a negative. (−6) × 3 = -18.
- 7.-5 — −10 ÷ 2 = -5 (unlike signs give a negative quotient).
- 8.8 — 48 ÷ 6 = 8 (unlike signs give a negative quotient).
- 9.9 — −18 ÷ (−2) = 9 (unlike signs give a negative quotient).
