Answer:
-27
Step-by-step explanation:
Just evaluate the brackets from the inner ones outwards...
11 - [ 7 - { 5 - 3 ( 9 - ( 3 - 6 ) ) } ]
= 11 - [ 7 - { 5 - 3 ( 9 - (-3) ) } ]
= 11 - [ 7 - { 5 - 3 ( 9 + 3 ) } ]
= 11 - [ 7 - { 5 - 3 ( 12 ) } ]
= 11 - [ 7 - { 5 - 36 } ]
= 11 - [ 7 - { -31 } ]
= 11 - [ 7 + 31 ]
= 11 - 38
= -27
