Answer key · Add and subtract integers
- 1.-11 — (−9) + (−2) = -11.
- 2.8 — 4 + 4 = 8.
- 3.-2 — 7 + (−9) = -2.
- 4.-1 — Subtracting is adding the opposite: 6 + (−7) = -1.
- 5.2 — Subtracting is adding the opposite: 6 + (−4) = 2.
- 6.-10 — Subtracting is adding the opposite: (−5) + (−5) = -10.
- 7.11 — Add left to right: 11 + (−4) = 7, then + 4 = 11.
- 8.-18 — Add left to right: (−11) + 4 = -7, then + (−11) = -18.
- 9.0 — Add left to right: 6 + (−1) = 5, then + (−5) = 0.
