Pretty self explanatory tbh This project runs WAY faster on turbowarp, and the list doesn't max at 200,000 numbers But anyway, when you press the green flag, enter the number you want to start checking if prime. The system will start checking, and then, once it is done, it will start checking if the next number is prime. The list to the right shows all the prime numbers bigger than your starting number currently checked.
I added an update that makes the system check the numbers 2x faster. It does this by ignoring even numbers, and moving on to odd numbers, as no even number is prime (except for 2). I am constantly working on updates to make the system faster. I also just released something that checks if the number is a multiple of 3 before it checks the rest of the numbers,
