Решение:
- \( 3 \times 18 - 64 : 4 = 54 - 16 = 38 \)
- \( (64 + 29) : 3 = 93 : 3 = 31 \)
- \( 4 \times 17 + 88 : 8 = 68 + 11 = 79 \)
- \( 65 - 48 : (81 : 27) = 65 - 48 : 3 = 65 - 16 = 49 \)
- \( 4 \times (12 - 25 : 5) = 4 \times (12 - 5) = 4 \times 7 = 28 \)
- \( 4 \times 12 - 25 : 5 = 48 - 5 = 43 \)
- \( 84 - 24 : 6 + 18 = 84 - 4 + 18 = 80 + 18 = 98 \)
- \( 81 - 54 : 18 + = 81 - 3 + = 78 \)
Ответ: 38, 31, 79, 49, 28, 43, 98, 78.
