8. 48 + 49 + 2. 69 - (26 + 24). 30 - 22. 80 - 4. 56 + 27 + 3. 69 - 26 + 24. 44 - 30. 84 - 5.

Решение:

1. \( 48 + 49 + 2 = 99 \)
2. \( 69 - (26 + 24) = 69 - 50 = 19 \)
3. \( 30 - 22 = 8 \)
4. \( 80 - 4 = 76 \)
5. \( 56 + 27 + 3 = 86 \)
6. \( 69 - 26 + 24 = 43 + 24 = 67 \)
7. \( 44 - 30 = 14 \)
8. \( 84 - 5 = 79 \)

Ответ: 99, 19, 8, 76, 86, 67, 14, 79.
