```   the numbers are:  13  62  101

the math is:  62 - 101 % 13 = 101 - 62 + 13

number system rs42Eval:  13(101 - 62) = 42
* 42 is the "Answer to Life, the Universe, and Everything"

BARSfunc rsAgeEval:  62 - sum_digits(13) + mult_digits(101) = 58
* MathBabbler was 58 years young when he saw this sign on TV.
* sum_digits(n) = sum the digits of n
domain:  n must be a prime number
* 13 is prime; sum_digits(13) = 1+3 = 4
* mult_digits(n) = product of the digits of n
domain:  n must be a prime number
* 101 is prime; mult_digits(101) = 1*0*1 = 0

BARSfunc math:  62 / reverse_digits(13) = sum_digits(101)
* reverse_digits(n) = the digits of n reversed
domain:  n must be a prime number
* 13 is prime; reverse_digits(13) = 31
* 101 is prime; sum_digits(101) = 1+0+1 = 2

BARSfunc rs42Eval:  101 - 62 + mult_digits(13) = 42
* 42 is the "Answer to Life, the Universe, and Everything"
* 13 is prime; mult_digits(13) = 1*3 = 3

BARSfunc rs37Eval:  101 - 62 + sqrt(sum_digits(13)) = 37
* Why rs37Eval? 37 Heaven @ http://thirty-seven.org
* 13 is prime; sum_digits(13) = 1+3 = 4

BARSfunc rsCardinalityEval:  spf(62) % cuberoot(101 + sum_digits(13)!) = 3
* There are three numbers in this road sign.
* spf(n) = the sum of the prime factors of n
domain: n must be a composite number
* 62 is composite; spf(62) = 2+31 = 33
