Первая таблица:
| \( 12 - 2 = 10 \) | \( 15 - 10 = 5 \) |
| \( 8 - 4 = 4 \) | \( 7 + 7 = 14 \) |
| \( 14 + 6 = 20 \) | \( 12 - 4 = 8 \) |
| \( 4 + 14 = 18 \) | \( 10 - 10 = 0 \) |
Вторая таблица:
| \( 12 - 2 = 10 \) | \( 15 - 10 = 5 \) |
| \( 17 - 4 = 13 \) | \( 17 + 0 = 17 \) |
| \( 14 + 6 = 20 \) | \( 12 - 4 = 8 \) |
| \( 13 + 4 = 17 \) | \( 18 - 10 = 8 \) |
Ответ: Первая таблица: 10, 4, 20, 18, 5, 14, 8, 0. Вторая таблица: 10, 13, 20, 17, 5, 17, 8, 8.
