### BARS::Street Cleaning and Speed Limit Signs from Warsaw, Illinois

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

The street signs say...

```     +-------+
| 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 = _______________________________________
