Answer 1

1.-

-12+26-8+15+23-20-25+10)

14 - 46 - 20 - 35

32 - 15=

17

2.-

-5+( -6)-(-5)+(-9)-(+7)+(-10)+7-12

-5-6+5-9-7-10 +7 - 12

-5 +11 -9-7 - +17 -12

+6 -9-7 - +17 -12

-3-7 - 5=

-14

3.-

[-6+(4-2)-(-9)] - [(-4)-(+7-5)+(-12)]+7-15

[-6+(+2)+9] - [-4 -(+2)-12]+7-15

[-6+2+9] - [-4 -2 -12]+7-15

[-6+11] - [-4-2-12]+7-15

[+5] - [-4-2-12]+7-15

[+5] - [-18]+7-15

rompemos corchetes

+5+18+7-15

+30-15

+15

4.-

4+{[-7+(3+2)-(-2)]+[(-3)-(+8-8) + (-10)]} +10-3=

4+{[-7+(+5)-(-2)]+[-3-(0)+(-10)]}+10-3

4+{[-7+5+2)]+[-3-10]}+10-3

4+{[-7+7]+[-3-10]}+10-3

4+{[0]+[-13]}+10-3

4+{-13}+10-3

4+{-13}+10-3

4-13 +10 -3

-9 +7 =

-2
