Question

Calcule o valor das expressões
A) (12+2.5)-8=
B) 25-(15+6:3)=
C) 25+[7+(8-4:2)]=
D) 60-[8+(10-2):2]=
E) 80-[22+(5.2+1)+6]=
F) 14:2+[13-(4.2+1)]=

Answer 1

A , (12+2.5)-8=
(12+10)-8=
22-8= *14*

B , 25-(15 +6 ÷3)
25-(15+2)
25-17= *8*

C, 25+ [7+(8-4:2)]
25+[7+(8-2)]
25+[7+6]
25+13= *38*

D,60-[8+(10-2):2]=
60-[8+8:2]=
60-[8+4]=
60-12= *48*

E) 80-[22+(5.2+1)+6]=
80-[22+(10+1)+6]=
80-[22+11+6]=
80-39 = *41*

F) 14:2+[13-(4.2+1)]=
7+[13-(8+1)]=
7+[13-9]=
7+4= *11*
