Math homework help!!!?

only in 7th grade, so don’t make your answer too complicated, make sure i could understand it.

ok, here’s the question:

We are now creating a new operation that will be represented by the symbol ‘@’. For example x and y… x @ y = x ^2 – y

Is @ an associative operation? Show examples to support your answer.

Help please!! you don’t have to do the question, just help as best as you can!!

In mathematics, associativity is a property that a binary operation can have. It means that, within an expression containing two or more of the same associative operators in a row, the order of operations does not matter as long as the sequence of the operands is not changed. That is, rearranging the parentheses in such an expression will not change its value. Consider for instance the equation

(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 :*

for this to be associative

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
