   the blurred road signs say...

      +--------------+ +------------------+
      | 10  East  60 | |         Exit 153 |
      |    Tucson    | | AZ 143 - 48th St |

   the numbers are:  2  6  9  3  7  10  60  153  143  48

   the math w/o HOV sign:  153 - 143 = 60 - 48 - 10base-2

   the math where the road signs equal the HOV sign:  
   153 - 143 - 10 + 60 - 48 = 9 + 7 - 2 * 6 / 3

   observe left-hand (road signs) side...
      153 - 143 = 10
      10 - 10 = 0
      0 + 60 = 60
      60 - 48 = 12

   observe right-hand (HOV sign) side...
      2 * 6 = 12
      12 / 3 = 4
      9 + 7 = 16
      16 - 4 = 12
