Ответ:
1) \(420 + 4900 : 70 - 22 \cdot 60\)
- \(4900 : 70 = 70\), \(22 \cdot 60 = 1320\).
- \(420 + 70 - 1320 = 490 - 1320 = -830\).
2) \((13\,335 + 12\,555) : 5 - 75 \cdot 34\)
- \(13\,335 + 12\,555 = 25\,890\).
- \(25\,890 : 5 = 5\,178\), \(75 \cdot 34 = 2\,550\).
- \(5\,178 - 2\,550 = 2\,628\).
Ответ: 1) −830; 2) 2628.
