Answer key · Add and subtract integers
- 1.7 — (−2) + 9 = 7.
- 2.-8 — 1 + (−9) = -8.
- 3.-5 — (−4) + (−1) = -5.
- 4.8 — Subtracting is adding the opposite: (−1) + 9 = 8.
- 5.-7 — Subtracting is adding the opposite: (−1) + (−6) = -7.
- 6.-10 — Subtracting is adding the opposite: (−4) + (−6) = -10.
- 7.-19 — Add left to right: (−6) + (−2) = -8, then + (−11) = -19.
- 8.4 — Add left to right: 11 + (−4) = 7, then + (−3) = 4.
- 9.8 — Add left to right: 4 + 1 = 5, then + 3 = 8.
