Favorite Answer
(5+2)+1 = 5+(2+1) = 8.
Even though the parentheses were rearranged, the value of the expression was not altered. Since this holds true when performing addition on any real numbers, we say that addition of real numbers is an associative operation.
Based on this , U can tell if @ is or isn’t associative.
Hope I could help :*
x@(y@z)=(x@y)@z
x@(y²-z)=(x²-y)@z
x²-(y²-z) = (x²-y)²-z
We can see from this that your operation is not associative
