Remix and replace the "x" on the left with any number you want to be aperialized. Rules: 1) Try not to be too complex with your number. 2) The maximum you can go is 2^32 - 1 (in which doesn't have a form), although parameters like ∞ are accepted. 3) Follow the Scratch TOS (I wrote this because I don't know what else to put here.) 4) If you want multiple numbers at once, the maximum is 10 at a time.
A blue "x" means that the number is prime and doesn't have a symbol yet. These are called "unlisted primes." A green "x" next to a number means the most square form of the number contains an unlisted prime as a factor. A cyan "x" means the number's most square form is made up of unlisted primes only. The more cyan x's, the more unlisted primes in the factorization.
