My lack of experience in other languages is showing, but whats the
advantage of an abstract method? how is that different than an

A purely abstract method in a super class is one that MUST be
overridden by a subclass.
So you cannot create an instance of the super class and the sub's
must provide this method.
Say you had some super class that had a "value" method
There's no way the super can implement any version of this for all
sub's but with an abstract it could force the subs to implement it.
