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]
