BARS::Two Miles From Boring, Oregon

This road sign was found on a road to Boring, Oregon.

To date, no math has been discovered using the number 212 found in the highway sign. We have math if the West OR Hwy-212 highway sign is removed.

   original:
   +------------------+
   | Boring         2 |
   | Oregon City   16 |
   +------------------+
   +--------+
   |  West  |
   | OR 212 |
   +--------+

   West OR 212 highway sign removed...

   +------------------+
   | Boring         2 |
   | Oregon City   16 |
   +------------------+
   the numbers are:  2  16

   the math is:  sqrt(sqrt(16)) = 2

   observe...
      sqrt(16) = 4
      sqrt(4) = 2

Across the road from the Boring sign was a road sign indicating we were 39 miles from Mt. Hood.

Update::2006.08.29

It was suggested during class that if 212 was split into three different numbers, there was math.

   the numbers are:  2  1  2  2  16

   that math is:  1 * 2^(2 + 2) = 16

   more math:  
      no or yes:  1 * 2^(2 * 2) = 16
      no or yes:  1 * 2^(2^2) = 16
      no or yes:  1 * (2 + 2)^2 = 16
      no or yes:  (2 * 2)^2 = 16^1
Update::2008.01.24

MathBabbler created the spf(n) function during late-November of 2007. The spf(n) function outputs the sum of the prime factors of its input n. spf(n) = n when n is prime.

This BAB was revisited using the 212 highway sign and the spf(n) function.

   the numbers are:  2  16  212

   the math is:  spf(spf(212)) + 2 = sqrt(16)!

   observe...
      spf(212) = 57
      spf(57) = 22
      22 + 2 = 24
      sqrt(16) = 4
      4! = 24            [factorial(4) = 4 * 3 * 2 * 1]
