I thought that was intentional; the copy for levels 3 and 4 heavily hint at what the values should be. The learner is encouraged to try and guess.<p>This is similar to the way that <a href="https:&#x2F;&#x2F;rubymonk.com&#x2F;" rel="nofollow">https:&#x2F;&#x2F;rubymonk.com&#x2F;</a> for example shows you how to do `2.even?` but doesn&#x27;t show you the equivalent method for checking if a number is odd.
