Gerald Thurman snapped this sign leaving Mesa, Arizona on Bush Highway heading up over Usery Park.

Mr. Thurman applies some nice math to get this winner.

\sqrt{87 - 14 + 10 - \sqrt{4}} = 9

This sign is on Bush Highway heading northbound out of Mesa, Arizona. See sign on map!

    Check this one

    Log10={ [87 - (4! x 3) ] - 14}

    Log10={[87- (24 x 3)] - 14}

    Log10={ [87-72] - 14}

    Log10={15 - 14}

    Log10=1

    perfect!!!!!

    Log10={ [87 - (4! x SQR9) ] - 14}

    Log10={[87- (24 x 3)] - 14}

    Log10={ [87-72] - 14}

    Log10={15 - 14}

    Log10=1

    Cesar, that is a nice application of log. However, on April 19th log was ruled out of RSM due to other problems with it particularly related to constants. Trigonometry functions were ruled out at the same time.

    Love to see the alternatives though!

    DEFENSE !!!!

    There is a simple formula for this sign with NO SQRT:

    87 + 9 = ( 14 + 10 ) x 4

    96 = 24 x 4

    [ This is a neat sign in what looks to be a really facinating place though. ]

    Math and a sign? What are you selling? I drive past this sign every weekend on the way to the lake. So what is all the math about and what are you trying to sell with that? I will not buy it. It’s a cheap sign out side of mesa and not a chalk board.
