BARS::100 E 1st St and 200 N Amherst Rd in Earth, Texas

These street signs are in Earth, Texas.

The street signs say...

   +------------------+
   | E 1st 100 St     |
   | N Amherst 200 Rd |
   +------------------+
   the numbers are:  1  100  200

   the math is:  log(sqrt(200 - 100)) = 1

   off-by-one math:  200 / 100 = 1 + 1

   BARSfunc math:  sqrt(sqrt(spf(200))) = 1 + log(sqrt(100))
   * spf(n) = the sum of the prime factors of n
   * spf(200) = 2 + 2 + 2 + 5 + 5 = 16
   * sqrt(16) = 4; sqrt(4) = 2
   * sqrt(100) = 10; log(10) = 1
Update::2009.09.20

MathBabbler was adding exercises to nBABs about the numbers 1109 (Earth's population) and 79031 (Earth's zip code) and that prompted him to re-visit this BARS using street signs from Earth.

   the numbers are:  1  100  200

   BARSfunc math:  log(spf(100) - sqrt(spf(200))) = 1
   * spf(n) = the sum of the prime factors of n
   * spf(100) = 2 + 2 + 5 + 5 = 14
   * spf(200) = 2 + 2 + 2 + 5 + 5 = 16; sqrt(16) = 4
   * 14 - 4 = 10; log(10) = 1

   number system off-by-one rsAgeEval:  200 / 1002 + 1 = 52 - 1
   * MathBabbler was 52 years young when he found this equation and
     RoadHacker was 52 years young when he found these street signs.
   * check w/Wolfram|Alpha

   [exercise] 1002 = ______
