Put in turbo mode(shift+green flag), click the green flag, say how many primes you want(2+), then wait. 'checkingnumber' is the number it's currently checking. 2.0-release 2.1-supposedly made doubly fast 2.2-made incredibly slightly faster
How it works: You only have to check if it's divisible by prime numbers, and also, you only have to check up to the square root, and you skip over even numbers.
