```   the numbers are:   4  31  32

rsCardinalityEval:  4 + 31 - 32 = 3
* There are three numbers in this road sign.

rsAgeEval:  32! / 31! + 4! = 56
* RoadHacker was 56 years young when he found this road sign.

rs37Eval:  31 + sqrt(4 + 32) = 37
* Why rs37Eval? 37 Heaven @ http://thirty-seven.org

off-by-one math:  32 - 31 = sqrt(4)-1

off-by-one rsAgeEval:  31 + 32 - 4 = 60-1
off-by-one rsAgeEval:  31 + 32 - sqrt(4) = 60+1
* MathBabbler was 60 years young when he created this BARS.
This BARS was created on 5/24 and MathBabbler turned 61

off-by-one BARSfunc rsStateEval:  sqrt(4) + reverse_digits(31) + 32 = 46+1
* Oklahoma was the 46th state admitted to the Union.
* reverse_digits(n) = the digits of n reversed
domain:  n must be a prime number
* 31 is prime; reverse_digits(31) = 13

off-by-one BARSfunc rs42Eval:  reverse_digits(31) + 32 - 4 = 42-1
