+--------------+
```
```   the numbers are:  20  30  50

the math is:  20 + 30 = 50

[solve for 'n']  n + 30 = 50

rsAgeEval:  log(30 - 20) + 50 = 51
* MathBabbler was 51 years young when he inserted this equation.

[exercise]  log(30 - 20) = _______
```

This road sign was posted to `RoadSignMath.com` and it received a RSM score of 9.2.

```   technical:  1
elegance:  (ln(20)/1.25 + ln(30)/1.25 + ln(50)/1.25) / 1 = 9.2

```   the numbers are:  20  30  50

rsAgeEval:  50 - ceil(30 / 20) = 48
* RoadHacker was 48 years young when he found this road sign.
* ceil(n) outputs 'n' rounded up to the nearest integer
* ceil(30 / 20) = ceil(1.5) = 2

rsAgeEval:  50 + ceil(30 / 20) = 52
* MathBabbler was 52 years young when he found this equation.

off-by-one rsHwyEval:  30 / log(20 * 50) = 9 + 1
* This road sign is on NM Hwy-9

another off-by-one rsHwyEval:  gcf(20, 30, 50) = 9 + 1
* This road sign is on NM Hwy-9

off-by-one rsAgeEval:  50 + log(30 - 20) = 52 - 1
* MathBabbler was 52 years young when he found this equation.

off-by-one rsAgeEval:  50 - log(30 - 20) = 48 + 1

...Base-9 can be used because this road sign was found on NM Hwy-9.
...Base-9 is the nonary number system.

number system rsStateEval:  50 - (209 / cuberoot(309)! = 47
* New Mexico was the 47th state admitted to the Union.

number system math:  209 + 309 = 509
