Let's create a custom class called Value that will hold a number.

Then add decorators that allow addition (Add) and subtraction (Sub) to a number (Value).

The Add and Sub decorators can accept integers directly, a custom Value object or other Add and Sub decorators.

Add, Sub and Value all implement the IValue interface and can be used recursively.
