+-------+ | Speed | | Limit | | 25 | +-------+ +------------+ | No Parking | | Fridays | | 4am - 6am | | Street | | Cleaning | +------------+the numbers are: 25 4 6 off-by-one math: 4 * 6 = 25 - 1 off-by-one math: ((4!) / 6)! = 25 - 1 function notation: factorial(factorial(4) / 6) = 25 - 1 off-by-one math: (6 / sqrt(4))! = sqrt(25) + 1 counting: 4, sqrt(25), 6 average math: avg(4, 6) = sqrt(25) mean math: mean(4, 6) = sqrt(25) rsAgeEval: 25 * (6 - 4) = 50 * RoadHacker found these signs when he was 50 years young. rsLucky7Eval: sqrt(25 + 6 * 4) = 7 * this BARS is the first rsLucky7Eval using BARS functions... more math: 4 + 6 = sum_prime_factors(25) [exercise] list the prime factors for 25 split_into_squares_sum(25) = { 16, 9 } the numbers become: 4 6 16 9 more math: sqrt(4) * 6 = sqrt(16) * sqrt(9) [exercise] get all sqrt(n) on one-side of the equation 6 = _______________________________________
