Give an example of where you would use either the Commutative or Associative Property of Addition in a real world situation.

So the best I could come up with is paper-rock-scissors; the operation takes two inputs and puts out the winner (assuming they are different).

So (paper rock) scissors = paper scissors = scissors,

But paper (rock scissors) = paper rock = paper.

This is a good example because it shows that associativity matters even outside of math.
