Question

(6.3+2.2+5.0) +12:3= ?
72:8+5.3-2=?
60+2{(4.(6+2)-10]+12}=?
58-[20-(3.4-2):5]=

Answer 1

(6.3+2.2+5.0) +12:3=
18+4+5+4=31


72:8+5.3-2=
9+15-2= -22


60+2{(4.(6+2)-10]+12}=
60+2{4{(8)-10]+12}=
60+2{32-10]+12=
60+2{22}+12=
60+44+12= 116



58-[20-(3.4-2):5]=
58-[20-(12-2):5]=
58-[20-10:5]=
58-[20-2]=
58-18=40
boa sorte
