2. Решите примеры: 75 — 32 : 8 8 • (92 — 84) (56 + 7) : 9 81 : 9 • 5 42 : 7 • 3 + 22 = 64 : 8 • 7 — 19 =

Решение:

1. \( 75 - 32 : 8 = 75 - 4 = 71 \)
2. \( 8 \times (92 - 84) = 8 \times 8 = 64 \)
3. \( (56 + 7) : 9 = 63 : 9 = 7 \)
4. \( 81 : 9 \times 5 = 9 \times 5 = 45 \)
5. \( 42 : 7 \times 3 + 22 = 6 \times 3 + 22 = 18 + 22 = 40 \)
6. \( 64 : 8 \times 7 - 19 = 8 \times 7 - 19 = 56 - 19 = 37 \)

Ответ: 71, 64, 7, 45, 40, 37.
