BARS::39 Miles South of Globe in Winkelman, Arizona

This road sign is on northbound AZ Hwy-77 in Winkelman, Arizona.

The road sign says...

   +-------------------+
   | Jct U.S. 70    36 |
   | Globe          39 |
   +-------------------+

This is the first BARS to use the spf function (sum of the prime factors).

   the numbers are:  70   36   39

   the math is:  spf(70) - sqrt(spf(39)) = spf(36)

   spf(70) = 14  (prime factors for 70: 2, 5, 7)
   spf(39) = 16  (prime factors for 39: 3, 13)
   spf(36) = 10  (prime factors for 36: 2, 2, 3, 3)

On 1 May 2008, MathBabbler wrote this C++ program to convert a string into a number. The program converts the string into the digits that MathBabbler needs to press on his cell phone in order to send the string as a text message. The number of the string-to-number conversion is the sum of the digits digits needed to send to enter the string as a text message.

     jct: 52228       (sums to 19) 
    u.s.: 887777      (sums to 65)
   globe: 45556662233 (sums to 47)
   the numbers become:  70  36  39  19  65  47

   the math is:  (47 - (39 - 36)) / (19 - (70 - 65)) = Pi

   observe...
      numerator:  39 - 36 = 3
                  47 - 3 = 44
      denominator:  70 - 65 = 5
                    19 - 5 = 14
      44 / 14 approximates Pi (3.14)

RoadHacker encountered this road sign again on 15 March 2013 as part of his Pi Day 2013 road trip.

   the numbers are:  70  36  39

   rs37Eval:  70 - 39 + sqrt(36) = 37
   * Why rs37Eval? 37 Heaven @ http://thirty-seven.org

   off-by-one rs42Eval: 70 % sqrt(36) + 39 = 42+1
   * 42 is the "Answer to Life, the Universe, and Everything"

   off-by-one rs42Eval: sqrt(70 % sqrt(36)) + 39 = 42-1
   * 42 is the "Answer to Life, the Universe, and Everything"

   off-by-one rsCardinality:  70 % (39 % sqrt(36))! = 3+1
   * There are three numbers in this road sign.
