How about you help us out by actually showing us some of your code?

The most likely reason is that you have not declared your classes as public, and they are outside of each others scope..

Also, if class A and class B have private or protected constructors then you wont be able to create instances of them, so you'd need to mark the methods Addition and Subtract as static.

Show us some code, and explain why you have marked the constructors as private and protected will better help us work out what you should be doing.
