{[(7×9-13)+6×4]:2+(200-143)×6} = {[(63-13)+24]:2+57×6} = [(50+24):2+342]=(74:2+342) = 37+342=379

31×{[(111+333+555):9-28]+3}:2=31×[(999:9-28)+3]:2=31×[(111-28)+3]:2=31×(83+3):2=31×86:2=2666:2=1333

{[(12×6-(132:2-72:6)]×3}-4={[(12×6-(66-12)]×3]-4=[(12×6-54)×3]-4=[(72-54)×3]-4=(18×3)-4=54-4=50

14×{[(96:3×16)×(50-50)]×1000}=14×{[(96:48)×0]×1000}=14×[(2×0)×1000]=14×(0×1000)=14×0=0

{[(455:5)+9]:10+2000-143}+(3×2)=[(91+9):10+2000-143]+6=(100:10+2000-143)+6=(10+2000-143)+6=(2010-143)+6=1867+6=1873
