Problem
What is the largest difference that can be formed by subtracting two numbers chosen from the set 
?
Solution
To maximize anything of the form 
, we maximize 
and minimize 
. The maximal element of the set is 
and the minimal element is 
, so the maximal difference is
![\[12-(-16)=28\rightarrow \boxed{\text{D}}.\]](http://latex.artofproblemsolving.com/4/1/3/4130909a3cf950d7c81705d012d16db74a7e91d2.png)
