Explicație pas cu pas:
205-[(5+24)×3-14]=205-(29×3-14)=205-(87-14)=205-73=132
203-[90:(4+33+8)+9]=203-(90:45+9)=203-11=192
181+[96-(3+30-4)-7]=181+(96-29-7)=181+60=241
a-28+(70:7-7)+175=500
a-28+3+175=500
a+150=500
a=500-150
a=350
a+19-(60-163)+238=480
a+19-(-103)+238=480
a+19+103+238=480
a+360=480
a=480-360
a=120
a-57+(435-200)+602=865
a-57+235+602=865
a+780=865
a=865-780
a=85
a+49-(918-644)+318=443
a+49-274+318=443
a+93=443
a=443-93
