Answer:
We use BODMAS here.
B stands for bracket, in which our order is ( )- { }- [ ].
O stands for 'of' which denotes multiplication.
D stands for division.
M also stands for multiplication, but should be done after 'of' only.
A stands for addition.
S stands for subtraction.
We follow this order for these kinds of simplifications, first simplifying brackets and lastly simplifying subtractions.
Given,
20- [ 9 - { 16 + ( 3 of 6 - 36 ) }]
Following the order, we simplify ( ) first.
Within ( ), we have (3 of 6 - 36)= 18 - 36 = -18
Next we go to { }. Here we have { 16 + (-18) }= { 16 - 18 }= -2
Coming to the square bracket we have [-9- {-2}]= -9 + 2= -7
Finally, we just simplify what is left over.
20- [-7]= 20 + 7= 27
