   +-----------------+
   | To I-27         |
   -------------------
   | West US  Hwy-60 |
   -------------------
   | South US Hwy-87 |
   +-----------------+
   the numbers are:  27  60  87

   the math is:  27 + 60 = 87

   rsAgeEval:  60 - 87 % cuberoot(27)! = 57
   * MathBabber was 57 years young when he created this BARS.

   BARSfunc rsCardinalityEval:  cuberoot(spd(87) - 60 % 27) = 3
   * There are 3 numbers in these highway signs.
   * spd(n) = the sum of the proper divisors of n
     domain: n must be a composite number
   * 87 is composite; spd(87) = 1+3+29 = 33
