This road sign is on eastbound NM Hwy-78 in New Mexico.

The road sign says...

+------------------+ | Mule Creek 9 | | Clifton, AZ 45 | | Safford, AZ 70 | +------------------+the numbers are: 9 45 70 rsAgeEval math: (45 / 9)! - 70 = 50 observe... MathBabbler was 50 years young when he found this road sign. 45 / 9 = 5 5! = 120 split_into_squares_sum(45) = { 36, 9 } split_into_squares_sum(70) = { 36, 25, 9 } the numbers become: 9 36 9 36 25 9 the math is: sqrt(36 / 9) + (36 / sqrt(9) - 9) = sqrt(25) observe... 36 / 9 = 4 sqrt(4) = 2 sqrt(9) = 3 36 / 3 = 12 12 - 9 = 3 2 + 3 = 5 = sqrt(25) more math: (sqrt(25) - (sqrt(9)! / sqrt(9)! + sqrt(9)! / sqrt(36)))! = sqrt(36) observe... sqrt(36) = 6 sqrt(9) = 3 3! = 6 more math: (36 + 9 + 9) / 9 = sqrt(36)! / sqrt(25)! observe... 36 + 9 + 9 = 54 54 / 9 = 6 sqrt(36) = 6 6! = 720 sqrt(25) = 5 5! = 120 720 / 120 = 6 the original numbers were: 9 45 70 sum_prime_factors(45) = 11 split_into_squares_sum(70) = { 36, 25, 9 } the numbers become: 9 11 36 25 9 the math is: 36 - 25 + 11 + 9 = 9
