29×3-38+[2000-(17×2+39×1:3)]=
87-38+[2000-(34+13)]=
49+(2000-47)=
49+1953=2002

68:2+[564:6+(31×2+15×3-117:3)]=
34+[94+(62+45-39)]=
34+(94+68)=
34+162=196

[(294:7×34):2]+350×100-34×21=
[(42×34):2]+35000-714=
(1428:2)+34286=
714+34286=35000

234:9[4000-(31+7)×15]:5-219:3=
26(4000-38×15):5-73=
26(4000-570):5-73=
26x3430:5-73=
26x686-73=
17836-73=17763

(31×3+74×5-32×9)-[2000:20+(1000-693)=
(93+370-288)-(100+307)=
175-407=
- 232
Sa verifici sa nu fie o greseala undeva in enunt, pt.ca mi-a dat rezultatul cu minus
