1. (90+54)-51= 144-51=89
2. 1799+[3x(127+273)+9]=1799+(3x400+9)= 1799+(1200+9)=1799+1209=3008
3. 12700-[176x6-438:3+(2+4)]=12700-(176x6-438:3+6)= 12700-(1056-146+6)=12700- 916=11784
4. [3000-3x122+7899]-2005= [3000-366+7899]-2005=10533-20058528
5. 2x[(0+18)+41-10]+999:9x3=2x(18+41-10)+999:9x3=2x49+111x3=98+333=426
