BARS::Clearance Signs on 1st Ave. in Phoenix, Arizona

These clearance signs were found on 1st Ave. in Phoenix, Arizona.

The clearance signs say...

   +-------------------------+
   | Enter-Clearance 6'-10'' |
   | Low Clearance   9'-1''  |
   +-------------------------+
   
   the numbers are:  6  10  9  1

   the math is:  sqrt(10 + 6) = sqrt(9) + 1

   observe...
      10 + 6 = 16
      sqrt(16) = 4
      sqrt(9) = 3
      3 + 1 = 4

   [exercise] find more math that doesn't use sqrt()
