For the last part, how do you generate random cases? Like addition, subtraction or multiplication. Thank you.

One way is to take what you did for cases 1-3 and put them in a case 4 where you randomly choose which option to do using a random number generator.  There are easier ways which you might be able to think of which involve less code, but what I mentioned is the more obvious one.

I don't get it by putting case 1-3 into case 4. Does that mean i should put another switch statement inside case 4?

No, i'm not sure if adding another switch statement is possible but if it were it'll probably complicate things a lot more. You'll need to have the 3 cases in the last case and to select a random one you'll need to use a extra number generator.
