Ответ:

  1. \(7 \cdot 4 + 6 \cdot 7 = 28 + 42 = 70\).
  2. \(9 \cdot 4 - 8 \cdot 4 = 36 - 32 = 4\).
  3. \(54 : 6 + 7 \cdot 4 = 9 + 28 = 37\).
  4. \(24 : 4 \cdot 7 - 32 = 6 \cdot 7 - 32 = 10\).
  5. \(48 + 72 : 9 = 48 + 8 = 56\).
  6. \(36 + 64 : 8 = 36 + 8 = 44\).
  7. \(60 - 7 \cdot 8 = 60 - 56 = 4\).
  8. \(39 + 32 : 4 = 39 + 8 = 47\).
  9. \(80 - 48 : 6 \cdot 5 = 80 - 8 \cdot 5 = 40\).
  10. \(36 + 54 : 9 \cdot 3 = 36 + 6 \cdot 3 = 54\).
  11. \(24 : 6 \cdot 8 - 16 = 4 \cdot 8 - 16 = 16\).
  12. \(71 - 6 \cdot 8 + 12 = 71 - 48 + 12 = 35\).
