   rsAgeEval:  50 - ceil(30 / 20) = 48
   * RoadHacker was 48 years young when he found this road sign.
   * ceil(n) outputs 'n' rounded up to the nearest integer
   * ceil(30 / 20) = ceil(1.5) = 2

   rsAgeEval:  50 + ceil(30 / 20) = 52
   * MathBabbler was 52 years young when he found this equation.

   off-by-one rsHwyEval:  30 / log(20 * 50) = 9 + 1
   * This road sign is on NM Hwy-9

   another off-by-one rsHwyEval:  gcf(20, 30, 50) = 9 + 1
   * This road sign is on NM Hwy-9

   off-by-one rsAgeEval:  50 + log(30 - 20) = 52 - 1
   * MathBabbler was 52 years young when he found this equation.

   off-by-one rsAgeEval:  50 - log(30 - 20) = 48 + 1
