Round 1
 1. – 5 + 9 = Answer 4 2. 17 + (– 10) + 3 = Answer 10 3. – 4 x (– 11) = Answer 44 4.  –8 – (– 8) + 10 = Answer 10 5.  20 + (– 14) – (+6) = Answer 0 6.  –12 + 5 – (– 3) = Answer -4 7.  –24 ÷ (– 12) = Answer 2 8.  40 – (– 20) + (– 30) = Answer 30 9.  10.5 + (– 4.5) – (6) = Answer 0 10.  – 12 x (– 8) = Answer 96
 11.  – 64 ÷ 8 = Answer -8 12.  32 + (– 9) – (–2)2 = Answer -4 13.  4 – (6 – 3) + (– 5) = Answer -4 14.  20 – 3 (– 6 + 4) – 8 = Answer 18 15.  (–42) ÷ (–7) – (–4)2 = Answer -10 16.  (–5) + (–6) + (–7) = Answer -18 17.  –45 ÷ 9 – (– 5) = Answer 0 18.  16 – (–6) ÷ (–2) = Answer 13 19.  – 7 + (–6) x (–2) = Answer 5 20.  9 x (–2) ÷ 6 = Answer -3

Round 2
 1.  8 + (–5) = Answer 3 2. 12 + (–15) – 6 = Answer -9 3. – 10 x (–8) = Answer 80 4.  –8 – (– 8) + 10 = Answer 10 5.  -10 + (– 10) – 20 = Answer -40 6.  –14 + 7 – (– 12) = Answer 5 7.  –5 ÷ (– 5) = Answer 1 8.  6 – (– 16) + (– 12) = Answer 10 9.  16 + (– 20) – (13) = Answer -17 10.  17 x (– 15) = Answer -255 11.  17 + (–7) – (5) + (–3) = Answer 2 12. (–1) – (–1)+(+1)+(–1) = Answer 0 13.  81 ÷ (–3) = Answer -27
 14.  –3 + (–9) – (12) = Answer -24 15. 10+(–11) –12 – (–13) = Answer 0 16. (–4)² – (–16) + (–13) = Answer 19 17.  25 – 3 (–12) – 30 = Answer 31 18.  7 – (6 –3) + 4 = Answer 8 19. –(–5 – 6) + (6 – (–8)) = Answer 25 20.  (3² – 4²) – (–5)² = Answer -32 21. +1 – 2 + 3 – 4 + 5 –6 = Answer -3 22.  15 – (–8 + 3) = Answer 20 23. –19 – (13–15) – (– 2) = Answer -15 24.  14 – (–16)+18 – 20 = Answer 28 25.  20 – (–2) + (–7 + 9) = Answer 24 26. (–45) x (–3) + (–15) = Answer 120
