title: Undefined method in console?
body: <p>Here comes another Codecademy question:</p>
  
  <p>The following challenge has been presented.</p>
  
  <blockquote>
    <p>Define two methods in the editor:</p>
    
    <p>A greeter method that takes a single string parameter, name, and
    returns a string greeting that person. (Make sure to use return and
    don't use print or puts.)</p>
    
    <p>A by_three? method that takes a single integer parameter, number, and
    returns true if that number is evenly divisible by three and false if
    not. Remember, it's a Ruby best practice to end method names that
    produce boolean values with a question mark.</p>
  </blockquote>
  
  <p>The code I put in re: was..</p>
  
  <pre><code>def greeter(name)
     return "Greet #{name}"
  end
  
  def by_three?(x)
     if x % 3==0
        returns true
     else
        return false
  end
  
  greeter("Brant")
  by_three?(6)
  </code></pre>
  
  <p>The console then gives me the following error:</p>
  
  <pre><code>Did you define your greeter method?
  </code></pre>
  
  <p>It seems like I have. Am I wrong?</p>
