- \(36:12\cdot(88:22)=3\cdot4=12\).
- \(85\cdot2+420:6=170+70=240\).
- \(56:14\cdot(66:33)=4\cdot2=8\).
- \(30\cdot3-450:9=90-50=40\).
- \(90:18\cdot(66:22)=5\cdot3=15\).
- \(75\cdot4-810:9=300-90=210\).
- \(18\cdot100:10=1800:10=180\).
- \(15000:1000\cdot10=15\cdot10=150\).
Ответ: 12; 240; 8; 40; 15; 210; 180; 150.
