Giup cho minh nhé
-452 - ( -67 + 75 - 452 )
= -452 + 67 - 75 + 452
= ( -452 + 452 ) + ( 67 -75 )
= 0 - 8
= 8
nho ket bạn với mình nha
- 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+67-75=-8
