Answer 1

Explicação passo-a-passo:

a) 10 - [ 7 - (6 - 8)]=

10 - [ 7 - (-2)]=

10 - [ 7+2]=

10 - 9=

1

b)10 : { 2 + [ 4+8]}=

10 : { 2 + 12}=

10 : 14=

10/14=

5/7

c) ( 25) - ( 2+9)=

25 - 11=

14

d) 2 . [ 6 - ( 10 +12) : 11]=

2 . [ 6 - 22 : 11]=

2 . [ 6 - 2]=

2 . 4=

8

e) { 5. [ 31 - 3 .7 +23] - 12}: 3=

{ 5 . [ 31 - 21 +23] - 12} : 3=

{ 5 . 33 - 12}: 3=

{ 165 - 12 } : 3=

153 :3=

51

f) 4 . { 9 . [ (8-5) . 4 +1] - 5}=

4 . { 9 . [ 3.4+1] - 5}=

4 . { 9 . [ 12 +1] - 5}=

4 . { 9 . 13 - 5}=

4 . { 117 - 5}=

4 . 112=
