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.
9/50 = 0.18
0.18*100 = 18%
1= a car tire
2= <span>A reflection would map your right shoe on your left shoe because your right shoe is a mirror image of your left shoe. </span>
The tax is 7.25% of $56.96.
7.25% of $56.96 =
= 7.25% * $56.96
= 0.0725 * $56.96
= $4.1296
The answer rounds to $4.13
The first 5 outputs are:
As you can see, the outputs keep doubling each time we increment x by 1.
This can be written formally, observing that if you know the value of 
, the next value will be
So, again, we've shown that the next value is twice the previous one, so you have
