Вопрос:

№3. Реши примеры: 12 + 2 × 9 − 25; 35 − 2 × 7 + 24; 62 − 3 × 9 − 12; 32 : 8 × 5; 16 : 4 × 3; 27 : 9 × 6; 65 × 0 : 6; 0 × 9 + 14; 14 : 2 : 7.

Ответ:

  1. \(12 + 2 \times 9 - 25 = 12 + 18 - 25 = 5\).
  2. \(35 - 2 \times 7 + 24 = 35 - 14 + 24 = 45\).
  3. \(62 - 3 \times 9 - 12 = 62 - 27 - 12 = 23\).
  4. \(32 : 8 \times 5 = 4 \times 5 = 20\).
  5. \(16 : 4 \times 3 = 4 \times 3 = 12\).
  6. \(27 : 9 \times 6 = 3 \times 6 = 18\).
  7. \(65 \times 0 : 6 = 0 : 6 = 0\).
  8. \(0 \times 9 + 14 = 0 + 14 = 14\).
  9. \(14 : 2 : 7 = 7 : 7 = 1\).
