Prime number finder

This program is exactly what it sounds like, it will determine if the number you entered is a prime number.
I found this very handy when I do things like long divisions.

@HarryPengRHS Well, the way I've learned it so far is in school, on a website called codeHS (, although I believe it's a fairly expensive set of courses, and it doesn't explain things in greater detail than the very basics. You could try to puzzle through , but I think that you'll find that YouTube is a perfectly fine (maybe even preferable) place to learn this stuff. Also, if you'd like, I can walk you through something if you'd like (but it's perfectly fine if you don't want my help on this, I'm not sure how you learn best, ha ha).
