6. Найди значения выражений: 32 + 28 − 20; 16 + 36 + 18; 90 − 24 + 14; 63 + 27 − 56; 38 − 27 + 79; 64 + 27 + 9; 32 − 16 + 40; 52 + 38 − 18.

1. \(32 + 28 - 20 = 60 - 20 = 40\)
2. \(16 + 36 + 18 = 52 + 18 = 70\)
3. \(90 - 24 + 14 = 66 + 14 = 80\)
4. \(63 + 27 - 56 = 90 - 56 = 34\)
5. \(38 - 27 + 79 = 11 + 79 = 90\)
6. \(64 + 27 + 9 = 91 + 9 = 100\)
7. \(32 - 16 + 40 = 16 + 40 = 56\)
8. \(52 + 38 - 18 = 90 - 18 = 72\)

Ответ: 40; 70; 80; 34; 90; 100; 56; 72.
