Question

Resuelve:

(12-6)-[1-(2_6)]=

(+9)-[(+3)-(3-12)-(+8)]=

(5-7)-[(-3)+(-6)]=

(9-6).(-2)+(13+3):(-4)=

Answer 1

6-[1+4]=6-5=1
9-[3+9-18]=9-[-6]=9+6=15
-2-[-3-6]=-2+9=7
3(-2)+16/-4=-6-4=-10

Answer 2

(12-6)-[1-(2_6)]=
(6)-(1-(-4))=
6-5=
1

(+9)-[(+3)-(3-12)-(+8)]=
(9)-[(3)-(-9)-(8)]=
9-(3+9-8)=
9-(4)=
5


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

(9-6).(-2)+(13+3):(-4)=
(3)(-2)+(16)/-4=
-6-4=
-10
