2 ) 41

3 ) 118

4 ) 21

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
