a - [932 - ( 314 -236 ) *3 ] :2 + 672 = 2000
a - ( 932 - 234 ) :2 = 2000 - 672
a - 349 = 1328
a = 1328 + 349
a = 1677
a - ( 932 - 234 ) :2 = 2000 - 672
a - 349 = 1328
a = 1328 + 349
a = 1677
168×4=672
2000-672=1328
a-[932-(314-236)×3]/2=1328
a-(932-78×3)/2=1328
a-(932-234)/2=1328
a-698/2=1328
a-349=1328
a=1677
2000-672=1328
