```   +--------------------------+
| Foothills Blvd         5 |
| Yuma                  19 |
| San Diego            196 |
+--------------------------+
```
```   the numbers are:  5  19  196

the math is:  19 - 5 = sqrt(196)

more math:  19 % sqrt(196) = 5

rsHwyEval:  sqrt(196) - 5! % 19 = 8
* This road sign was found on I-8

BARSfunc rsHwyEval:  spf(196 - summation(5, 19)) = 8
* This road sign was found on I-8

observe...
summation(5, 19) = 5+6+7+...+17+18+19 = 180
spf(n) = the sum of the prime factors of n
spf(196 - 180) = spf(16) = 2+2+2+2 = 8

rsDupEval:  summation(5, sqrt(196)) = dup(5) * 19

observe...
dup(5) = 5
summation(5, sqrt(196)) = summation(5, 14) = 5+6+7+...+12+13+14 = 95
