Ответ:

  1. \(18\,000 + 82\,000 + 24\,000 + 76\,000 = 200\,000\).
  2. \(140\,000 + (160\,000 + 840\,000) : 5 - 220\,000 = 140\,000 + 1\,000\,000 : 5 - 220\,000 = 140\,000 + 200\,000 - 220\,000 = 120\,000\).
  3. \((70\,000 : 2 - 5\,000) \cdot 3 - 16\,000 = (35\,000 - 5\,000) \cdot 3 - 16\,000 = 30\,000 \cdot 3 - 16\,000 = 74\,000\).
  4. \(171\,000 \cdot 0 + 350\,000 : 5 - 73 \cdot 0 : 1 = 0 + 70\,000 - 0 = 70\,000\).

Ответ: 200 000; 120 000; 74 000; 70 000.
