Hello everyone May i ask something?

I have been building a simple calculator. It works.but the system still shows that it is not perfect and there might be corner cases? What do corner cases mean?

A corner case means a case that can happen outside of normal usage of your app. you have to handle all the possible inputs the user can enter
