Ответ:

  1. \(8 \cdot 2 = 16\).
  2. \(2 \cdot 3 = 6\).
  3. \(6 \cdot 2 = 12\).
  4. \(21 : 3 = 7\).
  5. \(14 : 7 = 2\).
  6. \(24 : 8 = 3\).
  7. \(9 + (82 - 70) = 9 + 12 = 21\).
  8. \(95 - (50 - 43) = 95 - 7 = 88\).
  9. \((100 - 84) + 8 = 16 + 8 = 24\).
  10. \(94 - 25 = 69\).
  11. \(76 - 69 = 7\).
  12. \(58 + 16 = 74\).

Ответ: 16; 6; 12; 7; 2; 3; 21; 88; 24; 69; 7; 74.
