Works flawlessly, follows listed rules perfectly, but won't pass the "allowed operators" criteria I should start by mentioning that I know Wei Cui posted something that will pass in another person's question, but if I just copy and paste that I won't be learning why my own code is not validating. I can't seem to find any of the listed requirements I'm not in line with, and it works for all value
