Question

gente não sei essa contas vcs pode montar todas elas e colocar o resultado

Answer 1

b)25-[12-(3X2+1)]
   25-[12-(6+1)]
   25-[12-7]
   25-5 = 20

c)90-[25+(5X2-1)+3]
   90-[25+9+3]
   90-37 = 53

d)45+[(8X5-10:2)+(18:6-2)]
   45+[(40-5)+(3-2)]
   45+[35+1]
   45+36 =81

g)1000-[(2X4-6)+(2+6X4)]
   1000-[(8-6)+(2+24)]
   1000-[2+26]
   1000-28= 972



so consegui essas.

Answer 2

b)
25-[12-(3×2+1)]=
25-[12-(6+1)]=
25-[12-7]=
25-5=
20

c)
90-[25+(5×2-1)+3]=
90-[25+(10-1)+3]=
90-[25+9+3]=
90-[37]=
90-37=
53

d)
45+[(8×5-10÷2)+(18÷6-2)]=
45+[(40-5)+(3-2)]=
45+[35+1]=
45+36=
81

e)
50-2×{7+8÷2-[9-3×((5-4)]}=
50-2×{7+4-[9-3×1]}=
50-2×{7+4-[9-3}=
50-2×{7+4-[6]}=
50-2×(7+4-6)=
50-2×(11-6)=
50-2×5=
50-10=
40

f)
100-3×{5+8÷2-[3×(7-6)]}=
100-3×{5+4-[3×1]}=
100-3×{5+4-3}=
100-3×(9-3)=
100-3×(6)=
100-18=
82

g)
1000-[(2×4-6)+(2+6×4)]}=
1000-[(8-6)+(2+24)]=
1000-[2+26]=
1000-(28)=
1000-28=
972

h)
60+2×{[4×(6+2)-10]+12}=
60+2×{[4×8-10]+12}=
60+2×{[32-10]+12}=
60+2×{22+12}=
60+2×(34)=
60+68=
128

i)
[(4+16×2)×5-10]×100=
[(4+32)×5-10]×100=
[36×5-10]×100=
(180-10)×100=
170×100=
17000
