Simplification

Simplify: -12-|7-11|-[3-(-9)]

Ok I'm quite confused on where to even begin and how to end. Although, I think I must start with the numbers in the parantheses, am I correct? And will the outcome of |7-11| be positive?

Simplify: -12-|7-11|-[3- (-9) ] >>> Start with "dissolving" this parenthesis.

Start with this parenthesis.

And will the outcome of |7-11| be positive? <<< Yes

-12 -|7-11| - [3 - (-9)]

= -12 -|7-11| - [3 + 9]

= -12 -|- 4| - [3 + 9]

= -12 -|- 4| - [12]

= -12 - 4 - [12]

= -12 - 4 - 12

= - 28
