BARS::Parking Signs Behind Old Hardware Building in Tempe, Arizona

This parking sign was found in a parking lot behind the old hardware building located on Mill Avenue in downtown Tempe, Arizona.

The parking sign says...

   +------------------------+
   | Note your space number |
   |    Pay at meter 48     |
   --------------------------
   |       Pay Parking      |
   | 8 am - 4 pm            |
   | except Sundays         |
   | & Holidays             |
   --------------------------
   |        2  Hour         |
   |        Parking         |
   +------------------------+

   the numbers are:  2  4  8  48

       the math is:  48 / 8 - 4 = 2

This parking lot was also behind the Z Tejas Grill which is located at 20 W. 6th St. in Tempe. This parking sign picture includes the number 20 found on the back of Z Tejas.

   the numbers are:  2  4  8  20  48

   that math is:  sqrt(20 - 4) = 48 / 8 - 2

   observe...
      left-hand side
      20 - 4 = 16
      sqrt(16) = 4

      right-hand side
      48 / 8 = 6
      6 - 2 = 4

   pi off-by-one...

      48 / 4 + 20 / 2    12 + 10     22      22
      --------------- =  ------- =  ----    ---- approximates pi
             8              8         8       7

   more math from MAT102 students...

      1) 48 = 4 x 20 / 2 + 8

      2) 48 = 2(8 / sqrt(4) + 20)

In the 2nd BARS, the denominator in the fraction 22 / 8 is off-by-one with respect to the denominator in the fraction 22 / 7 that's used to approximate Pi. Calculate how much these two fractions really are off.
