Oops! Didn't notice this comment until after I got the email from Github re: pull request. However, I admit I noticed it failing for the "wrong" reason--that it didn't have a defined class. I hesitated about whether to send it on, but did so only because the first volley was a test for me that failed due to a method missing. So, I thought you'd just have to create the NegativeNumberError class and go from there.

That said, I agree with the ArgumentError choice -- I just wasn't familiar with that error type so didn't think to use it. I'll remember, even in errors, we're looking for the simplest thing.
