1) 11.101-(5.4+0.101)= 11.101-0.101-5.4=11-5.4=5.6 2) (9.5+1.8+1.39)+0.5+(0.61+5.2)=(9.5+0.5)+(1.8+5.2)+(1.39+0.61)= 10+7+2=19 3) (5.781+9.37)-4.781=5.781-4.781-9.37=1-9.37=-8.37 4)(3.23+8.596)+8.77=(3.23+8.77)+8.596=12+8.596=20.596 5)8.123-(2.123+1.8)=8.123-2.123-1.8=6-1.8=4.2 Вроде как все верно :3
