When I did the following problem, I got -12 as my answer. It is an evaluation problem, It looks like this:

Evaluate: -2^0[-2^0-2^2-(-2)^3-2](-2^0-2)+x-xy
When x= -3 and y= -4
I am unsure if this seems to be correct. If I made a mistake can someone please tell me where I need to make corrections. Thanks.

i got 8.25

it would help if you placed spaces after each addition and subtraction so it would be easier to read.
