BARS::Off-By-One rsAgeEval on AZ Highway-61 in Arizona

This road sign is on northbound AZ Highway-61 in Arizona.

The road sign says...

+----------------------+
| St. Johns         15 |
| Springerville     45 |
+----------------------+
   the numbers are:  15  45

   off-by-one rsAgeEval:  15 + 45 = 61-1
   * RoadHacker was 61 years young when found this road sign.
     [RoadHacker was 60 only three days earlier.]

   off-by-one rsHwyEval:  15 + 45 = 61-1
   * This road sign is only AZ Highway-61.

   off-by-one rsCardinalityEval:  45 / 15 = 3-1
   * There are two numbers in this road sign.

   * spf(n) = the sum of the prime factors of n
     domain: n must be a composite number
   * 15 is composite; spf(15) = 3+5 = 8
   * 45 is composite; spf(45) = 3+3+5 = 11

   BARSfunc rsCardinalityEval:  sqrt(15 - spf(45)) = 2
   * There are two numbers in this road sign.

   BARSfunc off-by-one rs42Eval:  45 - cuberoot(spf(15)) = 42+1
   * 42 is the "Answer to Life, the Universe, and Everything"

   BARSfunc off-by-one rsStateEval:  45 + cuberoot(spf(15)) = 48-1
   * Arizona was the 48th state admitted to the Union.
