    In today’s episode, I don’t understand the puzzle.
    We seem to be multiplying 5 arbitrary 1 digit number, but Kellams seems to get a result that is a 7 digit number. Shouldn’t the result be bounded by 9^5 = 59049?

    Hi, this is an editing flaw– multiply numbers together until you have a seven digit number!
