Answer key · Multiply and divide integers

1.
-1 — A negative times a negative is positive; unlike signs give a negative. 1 × (−1) = -1.
2.
40 — A negative times a negative is positive; unlike signs give a negative. 5 × 8 = 40.
3.
10 — A negative times a negative is positive; unlike signs give a negative. (−5) × (−2) = 10.
4.
-36 — A negative times a negative is positive; unlike signs give a negative. (−3) × 12 = -36.
5.
2 — A negative times a negative is positive; unlike signs give a negative. (−2) × (−1) = 2.
6.
8 — A negative times a negative is positive; unlike signs give a negative. 1 × 8 = 8.
7.
-6 — 24 ÷ (−4) = -6 (unlike signs give a negative quotient).
8.
3 — 15 ÷ 5 = 3 (unlike signs give a negative quotient).
9.
6 — −24 ÷ (−4) = 6 (unlike signs give a negative quotient).
