Solve the following python programming problem given the following code:
# From fluent python
class Demo():
    @classmethod
    def klassmeth(*args): # Class methods do not have to return an instance of the class
        return args
    
    @staticmethod
    def statmeth(*args): # This is just a regular function
        return args
    
    def instmeth(*args): # This is a true blue instance method
        return args
    

notademo = Demo.statmeth(1,2)
print(type(notademo))
notademo

ademo = Demo.klassmeth(1,2)
print(type(ademo))
ademo

ademo = Demo()
Demo.instmeth(ademo, 1,2)

ademo.instmeth(1,2)
Given the above code, generate some markdown instructions for it.

#Here is the Python code you requested.

Wouldn't it be great to define other operations (like addition and subtraction)?
Static Methods, Class Methods, Instance Methods
What's really going on under the hood here?
