Answer 1

Respuesta:

a) 18+[13+4-(5-7)+6=

18+(13+4-(-2)+6)

18+(13+4-(-2)+6

18+25

43

b)15-[12-3.4.4(-5)+10=

15-(12+240+10)

15-262

-247

c)18-[2-(4+5).(-4+9)]=

18-(2-9*5)

18-(2-45)

18(--43)

18+43

61

d)-[13-(12-6)]-[3.(-6)]=

-(13-6)-(-18)

-7+18

11

e)(5-4.5).[3-(-2).4.(-3)]=

(5-20)*(3+2*4*(-3))

-15(3-24)

-15*(-21)

315

f) [3-(5+15:3)]:[16-(-3).(-5)]=

(3-(5+5)):(16+3*(-5))

(3-10):(16-15)

-7:1

-7

g)15-[4.(-5+4.3)-3]+[32:(-8)]=

15-(4(-5+12)-3)+(-4)

15-(4*7-3)-4

15-(28-3)-4

15-25-4

-14

h)-[16-(8-5.6)]-(6-8:2).(-7)=​

-(16-(8-30))-(6-4)*(-7)

-(16-(-22))-2*(-7)

-(16+22)+14

-38+14

-24
