  1. Сначала умножение и деление: \(154\cdot78+3900:65-216\cdot53=12012+60-11448=624\).
  2. \(16728:82-5580:45+726\cdot29=204-124+21054=21134\).
  3. \((21518:53-24332:79)\cdot267=(406-308)\cdot267=98\cdot267=26166\).
  4. \((53734:67-59925:85)\cdot436=(802-705)\cdot436=97\cdot436=42292\).
  5. \((327\cdot84+207673):47=(27468+207673):47=235141:47=5003\).
  6. \((924\cdot93+30271):29=(85932+30271):29=116203:29=4007\).
  7. \((216\cdot28-463680:92):(86\cdot64-4496)=(6048-5040):(5504-4496)=1008:1008=1\).
  8. \((1004\cdot19-75110:37):(408\cdot435-177479)=(19076-2030):(177480-177479)=17046:1=17046\).
  9. \(61-(1428:136+4.3)\cdot3.4=61-(10.5+4.3)\cdot3.4=61-50.32=10.68\).
  10. \(40-(2550:204-6.9)\cdot6.7=40-(12.5-6.9)\cdot6.7=40-37.52=2.48\).
  11. \(37.72:4.6-(1.43+2.728)\cdot1.5=8.2-4.158\cdot1.5=8.2-6.237=1.963\).
  12. \(7.2\cdot3.8+(3.24-2.1312):0.42=27.36+1.1088:0.42=27.36+2.64=30\).
  13. \(3.564:0.66+0.4992:0.052-83\cdot0.107=5.4+9.6-8.881=6.119\).
  14. \(98\cdot0.035-0.0288:0.36-3:16=3.43-0.08-0.1875=3.1625\).
  15. \((0.084\cdot4.8-0.2132:6.5+0.0296):0.625=(0.4032-0.0328+0.0296):0.625=0.4:0.625=0.64\).
  16. \((0.056\cdot7.4+4.2106:7.4-0.0834):0.375=(0.4144+0.569-0.0834):0.375=0.3879:0.375=1.0344\).
  17. \((20.6-16.74)\cdot0.1+(23.4+8.95):100=3.86\cdot0.1+32.35:100=0.386+0.3235=0.7095\).
  18. \((0.326+3.724)\cdot100-(0.19682-0.0987):0.001=4.05\cdot100-0.09812:0.001=405-98.12=306.88\).
  19. \((2.04-1\frac{1}{4}):\frac{1}{20}=(2.04-1.25):0.05=0.79:0.05=15.8\).
  20. \((3.42-2\frac{5}{8}):\frac{1}{50}=(3.42-2.625):0.02=0.795:0.02=39.75\).
  21. \(23:(6\frac{5}{17}+1\frac{12}{17})-(4\frac{2}{5}-2\frac{3}{5}):5=23:8-1.8:5=\frac{23}{8}-\frac{9}{25}=\frac{503}{200}=2.515\).
  22. \((7\frac{4}{13}-4\frac{4}{13}):0.15-4:(13\frac{6}{13}+11\frac{7}{13})=3:0.15-4:25=20-0.16=19.84\).
