This project simply checks if a number is prime or not. Select a number using the slider and press spacebar to check. I basically used the property of prime numbers saying that if number p is prime, (p-1)!+1 must be divisible by p. I used the mod function to see if it was divisible, and then just changed the variable for prime or not? to match what I needed. Enjoy! It doesn't work for bigger numbers unless you download it though (since it rounds)
