How to Create Calculator Using C#

Building a calculator is a good learning project to do.
However, guidance would depend on your skill level.
Try something out and then post issues that you face here.

If you are a beginner, you can start with something basic.
Put a few buttons on the screen. Put some numbers on them and then start adding subtracting them.

Then move over to something more complex. Put those buttons in a collection and control them via that collection.

Simple progress like that will help you move ahead.
