Answer 1

- 9 - [ - 10 +(15-25) ]
-9 -[-10+(-10)]
-9-[-10-10]
-9-[-20]
-9+20
11

-----------


- 10 + 20 - [ - 8 - ( 9 + 6 - 13 )]

- 10 + 20 - [ - 8 - ( 2 )]
-10 +20 - [-10]
-10 +20 +10
20

------------------------------

15 + { 3 - [ - 11 - ( 13 + 14 ) - 7 ] } =
15 + {3 - [ -11 -(27) -7] }
15 + { 3 - [-45] }
15 + { 3 - 45 }
15 + { -42}
15 - 42
-27

--------------------------------

- 120 - [ - 32 + ( - 14 - 18 - 7 ) ]=

- 120 - [ - 32 + ( - 39 ) ]=

- 120 - [-71]
-120 + 71
-49

---------------------------------
300 - [ 70 + ( - 4 - 20 - 10 ) ]=

300 - [ 70 + ( -34 ) ]=

300 - [ 70 - 34 ]=

300 - [ 36 ]=
300 -36
264

-----------------------------------------

12 + { 4 - [ - 15 - ( 1 + 2 ) - 10 ] }=

12 + { 4 - [ - 15 - ( 3 ) - 10 ] }=

12 + { 4 - [ - 15 - 3 - 10 ] }=

12 + { 4 - [ - 28 ] }=

12 + { 4 + 28 }=
12 + {32}
12 + 32
44

Espero que te sirva
