Answer 1

Explicación paso a paso:

a).

[10-5(-2)]:(+5)+(-4+6)(+3)+8:(-2)=

[10+10]:5+2*3+(-4)

20:5+6-4

4+6-4=6

b).

(-9+6+5)(-4)+[7-(-8):(+2)-5]-(-3)=

2*(-4)+[7-(-4)-5]+3

-8+[7+4-5]+3

-8+[11-5]+3

-8+6+3=1

c).

[(11-4):(-7)+8](+2)-27:(+3)=

[7:(-7)+8]*(2)-9

[-1+8]*(2)-9

7*2-9

14-9=5

d).

[8-(-2)-(+5)(-3)](-3)+14:(-2)+(-5-2)(+1)=

[8+2-(-15)]*(-3)+(-7)+(-7)(+1)

[10+15]*(-3)-7+(-7)

25*(-3)-7-7

-75-14= -89
