Mình đặt tên a,b,c cho 3 ý cho dễ gọi nha.

a,\(-452-\left(-67+75-452\right)\)

\(=-452+67-75+452\)

\(=-8\)

b,\(35-\left\{12-\left[-14+\left(-2\right)\right]\right\}\)

\(=35-\left(12+14-2\right)\)

\(=35-24\)

\(=11\)

\(452-\left(67-75+452\right)\)

\(=452-67+75-452\)

\(=-67+75\)

\(=8\)

\(452-\left(67-75+452\right)\\ =452-67+75-452\\ =\left(452-452\right)-67+75\\ =-67+75\\ =8\)

- 452 - ( - 67 + 75 - 452 )

= - 452 + 67 - 75 + 452

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

=     0 + ( - 8 )

 =        - 8

mk đoán là -8 đúng ko 

-452-(-67+75-452)

=-452+67-75+452

=-8

-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

= 67 - 75

= -8
