Explicación paso a paso:
1 )
( 5 - 3 ) x [ ( - 6 ) + ( 5 + 1 ) - ( - 5 ) ] - [ ( 5 - 6 )
- ( - 7 + 9 ) - ( - 2 ) ]
= 3 x [ - 6 + 6 + 5 ] - [ - 1 - ( 2 ) + 2 ]
= 3 x [ 0 + 5 ] - [ - 1 - 2 + 2 ]
= 3 x 5 - [ - 1 + 0 ]
= 15 - [ - 1 ]
= 15 + 1
= 16
2 )
( - 5 + 7 - 3 ) - [ ( - 5 + 13 ) + ( - 3 - 1 ) + ( 4 - 5 ) +
9 x ( - 5 ) ]
= ( - 5 + 4 ) - [ 8 - 4 - 1 - 45 ]
= - 1 - [ 8 - 50 ]
= - 1 - [ - 42 ]
= - 1 + 42
= 41
3 )
( - 7 - 8 ) [ ( - 4 ) + ( - 4 + 2 ) - ( + 9 ) ] - [ ( 3 + 10 )
- ( - 18 + 9 ) + ( - 3 )
= ( - 15 ) [ - 4 - 2 - 9 ] - [ 13 - ( - 9 ) - 3
= ( - 15 ) [ -15 ] - 13 + 9 - 3
= 225 - 13 + 6
= 225 - 7
= 118
4 )
- 7 { 5 - [ ( - 10 + 2 ) + 4 - ( - 7 ) ] - ( 5 - 8 ) + 8 }
= - 7 { 5 - [ - 8 + 4 + 7 ] - ( - 3 + 8 ) }
= - 7 { 5 - [ - 8 + 11 ] - 5 }
= - 7 { 5 - 3 - 5 }
= - 7 { 5 - 8 }
= - 7 { - 3 }
= - 21
