### BARS::7 Miles From AZ Hwy-169 on I-17 in Arizona

This road sign is on southbound I-17 in Arizona. The picture was taken from the back of a Greyhound bus.

```   +-----------------------+
| AZ Hwy-169 South    7 |
| Cordes Jct         22 |
| Phoenix            87 |
+-----------------------+
```
```   the numbers are:  169  7  22  87

the math is:  87 % 7 = sqrt(22 - sqrt(169))

more math:  summation(sqrt(sqrt(169 + 87)), 7) = 22
* sqrt(169 + 87) = sqrt(256) = 16; sqrt(16) = 4
* summation(4, 7) = 4+5+6+7

rsPiEval:  log(sqrt(87 + sqrt(169))) * 22 / 7 ~= Pi
* 22/7 approximates Pi rounded to nearest hundredth (3.14)

rsAgeEval:  169 - 87 - 22 - 7 = 53
* RoadHacker was 53 years young when he found this road sign.

rsAgeEval:  sqrt(sqrt(169 + 87))! + 7 + 22 = 53
* RoadHacker was 53 years young when he found this road sign.

off-by-one math:  sqrt(169 + 87) + 7 = 22+1

off-by-one math:  87 % 22 - sqrt(169) = 7+1

BARSfunc math:  spf(87) - spf(16) + 7 = spf(22)
* spf(n) = the sum of the prime factors of n
* spf(87) = 3+29 = 32; spf(169) = 13+13 = 26; spf(22) = 2+11 = 13
