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       | | 1/4 Mile  |
                                   |    1/2 Mile    | | Exit Only |
                                   +----------------+ +-----------+

   the numbers are:  10  10  1  10  51  (1/2)  1  24  (1/4)

                  /---------- A ----------\     /------ B ----\
   the math is:  (10 + 10 + 10 + 24 - 1 - 1) - (sqrt(1/4) + 1/2) = 51

   observe...
      A = 10 + 10 + 10 + 24 - 1 - 1 = 52
      B = sqrt(1/4) = 1/2; 1/2 + 1/2 = 1
      A - B = 52 - 1 = 51
