The no parking sign says...

   +--------------+
   |  No Parking  |
   | Loading Zone |
   |  3am to 9am  |
   +--------------+
   the numbers are:  3  9

   the math is:  3 = sqrt(9)

   rsAllOdds:  3 and 9 are both odd numbers

   rsCardinalityEval:  log3(9) = 2
   * There are two numbers in this sign.

   rs42Eval:  summation(3, 9) = 42
   * 42 is the "Answer to Life, the Universe, and Everything"

   * dup(n) duplicates n (enables n to be used more than one)

   BARSfunc rsDupEval:  9 / 3 = dup(3)
   BARSfunc rsDupEval:  9 - 3! = dup(3)
   BARSfunc rsDupEval:  avg(3, 9) = dup(3)!
   BARSfunc rsDupEval:  cuberoot(9 * 3) = dup(3)
   BARSfunc rsDupEval:  gcf(3, 9) = dup(3)

   * spf(n) = the sum of the prime factors of n
     domain: n must be a composite number
   * 9 is composite; spf(9) = 3+3 = 6

   BARSfunc math:  3! = spf(9)
