### BARS::47 Miles From New Orleans, Louisiana

This road sign was on eastbound I-10 in Louisiana.

The road sign says...

```   +--------------------+
| US 61            3 |
| New Orleans     47 |
+--------------------+
```
```   the numbers are:  61  3  47

AllPrimesRS:  61, 3, 47 are all prime numbers
* BARS functions such as reverse_digits(n), sum_digits(n),
multi_digits(n) can be used when 'n' is a prime number.

rs42Eval:  (61 - 47) * 3 = 42
* 42 is the "Answer to Life, the Universe, and Everything"

off-by-one rsHwyEval:  61 - 47 - 3 = 10 + 1
* This road sign was found along I-10.

BARSfunc math:  47 % 3 = sqrt(sqrt(reverse_digits(61)))

BARSfunc rsHwyEval:  reverse_digits(47) - 61 - 3 = 10
* This road sign was found along I-10.

BARSfunc rsAgeEval:  reverse_digis(47) - reverse_digits(16) - 3! = 52
* RoadHacker was 52 years young when he found this road sign.

BARSfunc rsHwyEval:  sum_digits(47) - 3! / multiply_digits(61) = 10
* This road sign was found along I-10.

BARSfunc rsHwyEval:  sum_digits(47) - 61 % 3 = 10
* This road sign was found along I-10.

BARSfunc off-by-one rsAgeEval:  cuberoot(61 + 3) + 47 = 52 - 1
* RoadHacker was 52 years young when he found this road sign.

BARSfunc math:  sqrt(spf(61 - 47)) = 3
* spf(n) = the sum of the prime factors of n
* spf(61 - 47) = 14; spf(14) = 2+7 = 9; sqrt(9) = 3

BARSfunc rs42Eval:  47 - sqrt(sqrt(reverse_digits(61))) - 3 = 42
* 42 is the "Answer to Life, the Universe, and Everything"

* Louisiana was the 18th state admitted to the Union (1812).
