These road signs were found on westbound I-10 in Phoenix, Arizona.

The road signs say...

   +---------------------+ +----------------+ +----------+
   | Car Pools           | |        Exit 1A | |  Exit 1B |
   | Motorcycles         | | 10 East Tucson | | 24th St  |
   | and Buses Only      | | 51 North       | | 1/2 Mile |
   | 6am to 9am          | |     1 Mile     | +----------+
   | 3pm to 7pm  Mon-Fri | +----------------+
   +---------------------+

   the numbers are:  6  9  3  7  10  51  1  1  1  24  (1/2)

                 ------ A ------   ------- B -------
                 |             |   |               |
   the math is:  (6 + 9 + 3 + 7) x (24 x (1/2) - 10) + 1 + 1 - 1 = 51

   observe...
      A = 6 + 9 + 3 + 7 = 25
      B = 24 x (1/2) = 12; 12 - 10 = 2
      A x B = 25 x 2 = 50
      50 + 1 + 1 - 1 = 51
