Note that within a method in a class, it has direct access to other methods within the class.

@ is required if there is no attr_reader/attr_writer. Otherwise, Ruby automatically creates a method and the @ is unnecessary. I personally prefer to always use the @, though, because it makes it clear that it is an attribute.
