I'm having a problem with 'Object-Oriented Python' section 'Math' which uses magic methods.

The statement 'age = NumString(35)' creates an object of <class 'numstring.NumString'>, however, when I add one to 'age' with the expression 'age += 1' a new object is created of <class 'int'>. Therefore, I am assuming that additional 'dunder' methods have to be created to make the class work correctly. Which ones? How should they be implemented?

I am not sure the nature of your question, can you explain it a further?
