(a-406:2+29*4)-108:9=132
(a-203+116)-12=132
(a-203+116)=132+12
(a-203+116)=144
(a-203)=144-116
a-203 =28
a=28+203
a=231

(8×4+9×12-7×36)-(19+714:7-12×5)

(32+108-252)-(19+102-60)

(140-252)-(121-60)

(-112)-61

-173...altfel nu se poate face


(a-406:2+29×4)-108:9=132

(a-203+116)-12=132

a-203+116=132+12

a-203+116=144

a-203=144-116

a-203=28

a=28+203

a=231
