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

The road signs say...

   +-------------+ +-------------+ +----------------+ +-----------+
   | HOV 10 West | | 10 West     | |        Exit 1A | |   Exit 1B |
   +-------------+ | Los Angeles | | 10 East Tucson | |  24th St  |
                   +-------------+ | 51 North       | | Exit Only |
                                   |    Exit Only   | +-----------+
                                   +----------------+

   the numbers are:  10  10  1  10  51  1  24

                       A               B
   the math is: (10 - 10 + 10) x sqrt(24 + 1) + 1 = 51

   observe...
      A = 10 - 10 + 10 = 10
      B = sqrt(24 + 1) = sqrt(25) = 5
      A x B = 10 x 5 = 50
      50 + 1 = 51
