This may be a stupid question but are not the basics of all these four functions almost the same? You have two operands and an operator which together will produce a result. Think about your addition algorithm and how similar the other operations are.

Well we cannot guess what happens when you try, you need to explain in detail and show the code that is not working. Please edit your question with the required information.
