The only equations contained in this BARS when it was
posted were rsAgeEvals and the equations used the BARS
functions:  floor(n), ceil(n), spf(n).

BARSfunc rsAgeEval:  51 + floor(74 / 39) = 52
* 74 / 39 = 1.897435897435897435...
* floor(1.897435) = 1

BARSfunc rsAgeEval:  51 + ceil(39 / 74) = 52
* 39 / 74 = 0.52702702702...
* ceil(0.52702) = 1

observe...
spf(n) = the sum of the prime factors of n
spf(39) = 3 + 13 = 16
spf(51)= 3 + 17 = 20
spf(74) = 2 + 37 = 39

BARSfunc rsAgeEval:  51 + spf(74) / 39 = 52
51 +    39   / 39 = 52
51 +         1    = 52

BARSfunc rsAgeEval:  74 - sqf(51) - sqrt(sqrt(spf(39)) = 52
74 -    20   - sqrt(sqrt(  16   ) = 52
74 -    20   - sqrt(      4     ) = 52
74 -    20   -           2        = 52
