Wait...is it sad that you agree with me, or sad that no one solved the problem? |

 OK, since no one is getting this, I will guess. And guess wrong I will. This is in no means a real 'proof.' Any number multiplied by two (or any even number) will have all of its digits double, therefore no odd numbers will remain in the product (except several ones.) Hey - don't make fun of me. At least I TRIED.  P.S. - NEW QUESTION!! |

37 * 2 = 74. 7 is odd. Good try though. |

This is the problem of the WEEK, not the problem of the month. No one is solving it, can't we get a new question? |

Solve the problem and it will be changed. Good try Myself, but it's a bit more complicated than that. |

Then do so and I will consider it solved. Good luck, though, on that.... |

Okay, I think I have it. X = persistent # (n)(X) = persistent number (n) = number Let's say we make n = 3. 3X = persistent # Now let's divide by 3. X = (persistent number)/3 Since X is a persistent number, that would mean... persistent # = (persistent #)/3 Therefore, no persistent number can be multiplied by 3. |

You missed the fact that the persistent numbers will be different. Obviously through the way you defined it, persistent #1 = (persistent #2)/3. |
