Another demo, this one all about the math! Press [space] to have it assemble a list of all the primes between 1 and the inputted number. Note that this can take a while if you put in too large a number. AKA, please do not use this to verify the 24,862,048-digit largest (currently) found prime. Or, considering it takes over 13 minutes to go from 10,000 to 100,000, anything remotely close to that length. You can also press [a] to just factor a number. It will need to calculate the primes up to that number if the list isn't long enough at the moment, but overall is usually shorter. Updates: -Significantly improved efficiency -Time tracker
