AYUDENME CON TODO Y PROCEDIMIENTO

Answer 1

1. -4+(-3)-8+(-2)=
-4-3-8-2=
-17
2. -8+(-2)-(-5)=
-8-2+5=
-5
3. -3+(-5)-(-5)+(-4)=
-3-5+5-4=
-7
4. -14+9+6-(-10)=
-14+15+10=
12
5. -9-(-9)+12-(-12)=
-9+9+12+12=
24
6. 5+4-[(-4)-(7-(-(-3)))]-4=
5+4-[(-4)-(7-(+3))]-4=
5+4-[(-4)-(7-3)]-4=
5+4-[-4-7+3]-4=
5+4+4+7-3-4=
20-7=
13

7. -[-{[(3)+(-2)]-[(-5)+(-9)]}]=
-[-{[3-2]-[-5-9]}]=
-[-{3-2+5+9}]=
-[-3+2-5-9]=
+3-2+5+9=
17-2=
15
