Question

d) (−6)0 + (−3)2 + (−2). (−1) =


e) (−6)2 − 12 =


f) 20 –{-10 –[-8 +(5 -12)] -20}=​

Answer 1

Explicação passo-a-passo:

d) 1 + (+9) + (+2)= 1+9+2= + 12

e) (+36) - 12= +24

f) 20 - { - 10 - [ -8 + ( - 7)] - 20}=

20 - { - 10 - [ -8-7-20]=

20 - { - 10 - [ - 35}=

20 - { - 10 + 35}=

20 - { + 25}=

20 - 25=

- 5
