Problem
Define 
to be 
for all real numbers 
and 
What is the value of ![\[(1\diamond(2\diamond3))-((1\diamond2)\diamond3)?\]](http://latex.artofproblemsolving.com/3/0/a/30abfad2fabbf18f3fae4d47e45fdcc4bf8a8d94.png)
Solution
We have 
~MRENTHUSIASM
Solution 2
Observe that the 
function is simply the positive difference between two numbers. Thus, we evaluate: the difference between 
and 
is 
; the difference between and is 
; the difference between and is ; the difference between and is ; and finally, $0-2=\boxed{\text{(A)}~-2.$ (Error compiling LaTeX. Unknown error_msg)
