BARS::Loop 202 at I-10 in Chandler, Arizona

These road signs were found on westbound Loop 202 at its junction with I-10 in Chandler, Arizona.

The road signs say...

   +-----------+ +------------+
   | Exit  55A | | Exit  55B  |
   | 10 Tucson | | 10 Phoenix |
   +-----------+ +------------+

   the numbers are:  55  10  55  10

   the math is:  sqrt(55 + 55 - 10) = 10

Generally, road signs containing four numbers--only two of which are unique--are ignored because of trivial math.

   trivial math:
      55 + 10 = 10 + 55  [commutative]
      55 - 55 = 10 - 10
      55 x 10 = 10 x 55  [commutative]
      55 / 55 = 10 / 10
      55 / 55 = (10 - 10)!
