Question

calcule o valor das expressões:
a)16+[10-(18÷3+2)+5]=
b)45+[(2×4-6)+(2+6×4)]=
c)1000-[(2×4-6)+(2+6×4)]=
d){10+[5×(4+2×5)-8]×2}-100=

Answer 1

a)16+[10-(6+2)+5]=
16+[10-8+5]=
16+7=23

b)45+[(8-6)+(2+24)=
45+[2+26]=
45+28=73

c)1000-[(8-6)+(2+24)]=
1000-[2+26]=
1000-28=972

d){10+[5×(4+10)-8]×2}-100=
{10+[5×14-8]×2}-100=
{10+[70-8]×2}-100=
{10+68×2}-100=
{10+136}-100=
146-100=46
