Could you be more specific? Like what exactly is the problem? Can you show some code too?

There are a huge number of ways you could do this, and exactly what type of calculator you want to produce and the environment you are working in will determine a lot of factors.

So sit down, work out exactly what you want to produce:
1) A "traditional" calculator with separate on-screen buttons for each key
2) A "modern" calculator such as Microsoft Mathematics where you type in a string such as "102+405=" and it works it out from there.

Then work out what environment you will be working in - Console, WinForms, WPF, or web-based for example - and think about how you will need to implement in that environment.

But we aren't going to do it for you - you learn nothing useful if we do your homework for you!
So try it yourself, you may find it is not as difficult as you think!

If you meet a specific problem, then please ask about that and we will do our best to help. But we aren't going to do it all for you!
