Ответ:

  1. 3⋅8 : 6 = 24 : 6 = 4
  2. 6⋅4 : 3 = 24 : 3 = 8
  3. 9⋅4 : 6 = 36 : 6 = 6
  4. 14 : 2⋅7 = 7 ⋅7 = 49
  5. 27 : 3⋅9 = 9⋅9 = 81
  6. 32 : 4⋅8 = 8 ⋅ 8 = 64
  7. 56 – (32 – 4) = 56 – 28 = 28
  8. 85 – (65 + 20) = 85 – 85 = 0
  9. 90 – (62 – 20) = 90 – 42 = 48
  10. 0 : 9 = 0
  11. 0 : 24 = 0
  12. 0 ⋅ 33 = 0

Ответ: 4, 8, 6, 49, 81, 64, 28, 0, 48, 0, 0, 0
