- The following problem is from both the 2022 AMC 10B #1 and 2022 AMC 12B #1, so both problems redirect to this page.
Problem
Define 
to be 
for all real numbers 
and 
What is the value of ![\[(1\diamondsuit(2\diamondsuit3))-((1\diamondsuit2)\diamondsuit3)?\]](http://latex.artofproblemsolving.com/e/4/8/e486594a9c3be11fd5275aa45b53a4aecf616093.png)
Solution
We have ![\[(1\diamondsuit(2\diamondsuit3))-((1\diamondsuit2)\diamondsuit3)=(1\diamondsuit1)-(1\diamondsuit3)=0-2=\boxed{\textbf{(A)}\ {-}2}.\]](http://latex.artofproblemsolving.com/5/7/1/57150d8c9cde5436d44e6843b310bdcb780e2958.png)
