Question 565341: Please tell me if I'm working this out right..

First I did what was in []... (-2*-2)-2|-2= (4)-2|-2|= 0
Is that right so far?
Then I took the numerator.. -2*-2= 4 So, now it's 4/ 2-2*0= 4/0 or 4.
Am I even close? It's been a very long time since I learned this stuff. I only hope you're seeing the equation as I am. Thanks for your help.
