1. \(838 008 : 9 - 410 960 : 8\)
\(838 008 : 9 = 93112\)
\(410 960 : 8 = 51370\)
\(93112 - 51370 = 41742\)
2. \(1 482 \cdot 50 + 6 700 \cdot 30\)
\(1 482 \cdot 50 = 74100\)
\(6 700 \cdot 30 = 201000\)
\(74100 + 201000 = 275100\)
3. \(560 000 : 100 \cdot 8\)
\(560 000 : 100 = 5600\)
\(5600 \cdot 8 = 44800\)
4. \(283 040 : 10 \cdot 9\)
\(283 040 : 10 = 28304\)
\(28304 \cdot 9 = 254736\)
