Scuze dar ultima n-am stiut sa o fac

Answer 2

13x9-48:6+12650=
117-8+12,650=
109+12,650=12,759.


32x17+7095:165-78:26=
544+43-3=
544+40=584


2002+{[150-(26x15-95x3)x2]x3-24x5}=
2002+{[150-(390-285)x2]x3-120}=
2002+[(150-105)x2x3-120]=
2002+(45x2x3-120)=
2002+(90x3-120)=
2002+(270-120)=
2002+150=2152
