- 452 - ( - 67 + 75 - 452 )
= - 452 + 67 - 75 + 452
= [(- 452 ) + 452 ] + ( 67 - 75 )
= 0 + ( - 8 )
= - 8
-452 - ( -67 + 75 - 452 )
= -452 + 67 - 75 + 452
= ( -452 + 452 ) + ( 67 - 75 )
= 0 + ( -8 )
= -8
-452 - ( - 67 + 75 - 452 )

= (-452 + 452) + 67 - 75
= 0 + 67 - 75
= 67 - 75
= -8

Tớ không biết có đúng hay không .
Đề nghị nếu tớ giải sai đừng xách dép dí tớ à nha

nho ket bạn với mình nha
- 452 - ( - 67 + 75 - 452 ) =
= - 452 + 67 - 75 + 452
= [ ( - 452 ) + 452 ] + ( 67 - 75 )
= 0 + ( - 8 )
= - 8
d: =-452+67-75+452=-8
e: \(=1997-\left[10\cdot8:8+8\right]=1997-11=1986\)
