Question

calcule cu paranteză pătrată rotundă

Answer 1

200-[(872:8+324:9)×54-7730]=
200-[(109+36)×54-7730]=
200-(145×54-7730)=
200-(7830-7730)=
200-100=
100


{[11-(100:5-171:9)]×10}:100=
{[11-(20-19)]×10}:100=
[(11-1)×10]:100=
(10×10):100=
100:100=1

[25+(425-8×10×5)×4]:5+75=
[25+(425-400)×4]:5+75=
(25+25×4):5+75=
(25+100):5+75=
125:5+75=
25+75=100


{90+[100+(11×4+7×8):10]-80}:60=
{90+[100+(44+56):10]-80}:60=
[90+(100+100:10)-80]:60=
[90+(100+10)-80]:60=
(90+110-80):60=
(200-80)÷60=
120:60=2



{90-35:[4×(29-7×3)-25]}×10=
{90-35:[4×(29-21)-25]}×10=
[90-35:(4×8-25)]×10=
[90-35:(32-25)]×10=
(90-35:7)×10=
(90-5)×10=
85×10= 850


{45+[9×10+(32×4-7×4):10]}:5=
{45+[9×10+(128-28):10]}:5=
[45+(9×10+100:10)]:5=
[45+(90+10)]:5=
(45+100):5=
145:5=29
