Ответ:
- \(40-30+63:7=40-30+9=19\)
- \(97-51-8\cdot5=97-51-40=6\)
- \(48:6+(57-34)=8+23=31\)
- \(88-(45:9)\cdot4=88-5\cdot4=68\)
- \(6\cdot(5+7)-6\cdot8=6\cdot12-48=24\)
- \(9\cdot(2+7)-54=9\cdot9-54=27\)
- \(81:(90:10)-7=81:9-7=2\)
- \((71-36):5+29=35:5+29=36\)
- \(96-(36:6):2=96-6:2=93\)
- \(87-(63:9)\cdot10=87-7\cdot10=17\)
- \((45:9)\cdot(8:4)=5\cdot2=10\)
- \(35:(7\cdot1)\cdot6=35:7\cdot6=30\)
- \(10\cdot3-10\cdot2=30-20=10\)
- \(63:(72:8)=63:9=7\)
- \(33+(14-2):3=33+12:3=37\)
- \(7\cdot8-16+37=56-16+37=77\)
- \(10\cdot10-5\cdot9=100-45=55\)
- \(2\cdot(15:3)\cdot7=2\cdot5\cdot7=70\)
