Решение:

1. \( 35 : 5 + 82 - 65 + 21 + 1 = 7 + 82 - 65 + 21 + 1 = 89 - 65 + 21 + 1 = 24 + 21 + 1 = 45 + 1 = 46 \)
2. \( 9 \cdot 2 + 8 \cdot 7 - (83 - 54) = 18 + 56 - 29 = 74 - 29 = 45 \)
3. \( 7 + 42 : 6 + 19 + 58 + 7 = 7 + 7 + 19 + 58 + 7 = 14 + 19 + 58 + 7 = 33 + 58 + 7 = 91 + 7 = 98 \)
4. \( 9 \cdot 4 + 54 : 9 + 28 - 8 = 36 + 6 + 28 - 8 = 42 + 28 - 8 = 70 - 8 = 62 \)
5. \( 85 - 9 \cdot 4 + 7 + 4 - 7 \cdot 4 = 85 - 36 + 7 + 4 - 28 = 49 + 7 + 4 - 28 = 56 + 4 - 28 = 60 - 28 = 32 \)
6. \( 3 : 3 \cdot 9 + 18 : 2 - 2 \cdot 4 = 1 \cdot 9 + 9 - 8 = 9 + 9 - 8 = 18 - 8 = 10 \)
7. \( 66 - 35 - 5 \cdot 2 + 27 + 22 = 66 - 35 - 10 + 27 + 22 = 31 - 10 + 27 + 22 = 21 + 27 + 22 = 48 + 22 = 70 \)
8. \( 65 - 3 - 36 : 4 + 34 - 23 = 65 - 3 - 9 + 34 - 23 = 62 - 9 + 34 - 23 = 53 + 34 - 23 = 87 - 23 = 64 \)

Ответ: 46; 45; 98; 62; 32; 10; 70; 64.
