Ответ:
| 7 + 7 − 14 | 22 − (21 + 1) | 8 + 9 − 1 | 70 + 20 + 9 | (77 − 70) + 9 |
|---|---|---|---|---|
| 14 − 14 = 0 | 22 − 22 = 0 | 17 − 1 = 16 | 90 + 9 = 99 | 7 + 9 = 16 |
| (6 + 6) − 10 | 65 − 5 + 40 | 63 − (30 + 30) | 18 − (16 − 8) | (43 + 1) − 40 |
| 12 − 10 = 2 | 60 + 40 = 100 | 63 − 60 = 3 | 18 − 8 = 10 | 44 − 40 = 4 |
| 90 − 1 − 80 | 6 + (15 − 7) | 94 + (11 − 10) | 30 − 1 + 0 | 8 + (19 + 1) |
| 89 − 80 = 9 | 6 + 8 = 14 | 94 + 1 = 95 | 29 + 0 = 29 | 8 + 20 = 28 |
