65+ [34 x (427+568) -(671-293)] =

65+(34×995-378)=

65+(33.830-378)=

65+33.452=33.517

28 x 26 + 25 x [208- (707-568)]=

728+25×(208-139)=

728+25×69=

728+1725=2453

14 700 +799-45 x[45+ (800-75):25] =

14.700+799-45×(45+725:25)=

14.700+799-45×(45+29)=

14.700+799-45×74=

14.700+799-3330=

15.499-3330=12.169
