+------------------+ | Florence 16 | | Tucson 83 | +------------------+the numbers are: 16 83 rsHwyEval: 83 - sqrt(16) = 79 * This road is on southbound AZ Hwy-79. PrimeAndSquareRS: 16 is a square number; 83 is a prime number note: 83 is a "cousin prime" with prime number 79 and this road sign is on AZ Hwy79. off-by-one rsCardinality: 83 % sqrt(sqrt(16)) = 2-1 * There are two numbers in this road sign. off-by-one rsCardinality: sqrt(sqrt(83 - sqrt(sqrt(16)))) = 2+1 * There are two numbers in this road sign. BARSfunc math: sqrt(16)! = mult_digits(83) * mult_digits(n) = product of the digits of n domain: n must be a prime number * 83 is prime; mult_digits(83) = 8*3 = 24 BARSfunc rsCardinalityEval: cuberoot(16 + sum_digits(83)) = 3 * sum_digits(n) = sum the digits of n domain: n must be a prime number * 83 is prime; sum_digits(83) = 8+3 = 11 off-by-one BARSfunc rsAgeEval: 16 + reverse_digits(83) = 55-1 * RoadHacker was 55 years young when he found this road sign. * reverse_digits(n) = the digits of n reversed domain: n must be a prime number * 83 is prime; reverse_digits(83) = 38
