6×9:[6-(13-18:2)]=
[(9-6)×(8+9)]+100:(4+6)=
5×[3600:30-81:(54:6)]=
128:4+[2×(2222:22-22:22)]=
36:9+4×[20+6×(100:4-42:2)]=
126-[(63×2:6+109)×(75:25+21:3)]:10=

Answer 1

6×9:[6-(13-9)]=
6×9:(6-4)=
6×9:2=
54:2=27

(3×17)+100:10=
51+10=61

5×(3600:30-81:9)=
5×(120-9)=
5×111= 555

128:4+[2×(101-1)]=
128:4+(2×100)=
128:4+ 200=
32+200=232

36:9+4×[20+6×(25-21)]
36:9+4×(20+6×4)
36:9+4×(20+24)
36:9+4×44
4+176=180

126-[(126:6+109)×(3+7)]:10=
126-[(21+109)×10]:10=
126-(130×10):10=
126-1300:10=
126-130= -4

Scuze, la ultima nu mia dat cum trebuia. Sper ca te-am ajutat
