These street signs are on Main Street in Warsaw, Illinois.

The street signs say...

     +-------+
     | Speed |
     | Limit |
     |  25   |
     +-------+

   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 = _______________________________________
