This road sign is painted into a mural found in Pacific Beach, California.

The muralized road sign says...

+------------------------+
| La Jolla             4 |
| Los Angeles        123 |
| Mission Beach        1 |
| Ocean Beach      3 1/2 |
| San Diego           10 |
+------------------------+
the numbers are:  4  123  1  3.5  10

the math is:  sqrt(123 - sqrt(4)) - 10 = 1^(3.5)

rsAgeEval:  (4^3.5 - 123) * 10 + 1 = 51
* RoadHacker was 51 years young when he found this mural.

rs42Eval:  123 / floor(3.5) + sqrt(4) - (1 - log(10))! = 42
* 42 is the "Answer to Life, the Universe, and Everything"

more math:  log(sqrt(123 - sqrt(4) * 10 - floor(3.5))) = 1

more math:  123 - 10^sqrt(4) + 1 = ceil(3.5)!

more math:  (4 * 10 + 1) * floor(3.5) = 123

more math:  sqrt(123 - reciprocal(4 - 3 1/2)) - 1 = 10
Exercises
1. Solve for n:    123 - 10^sqrt(4) + n = 24

2. Solve for n:    (n * 10 + 1) * 3 = 123

3. Solve for n:    (4^n - 123) * 10 + 1 = 51

4. Solve for n:    log(sqrt(123 - 4^(1/2) * n - 3)) = 1
hint: sqrt(n) = n^(1/2)

5. The number 123 is semiprime (or biprime) because it has only two prime factors and they are _____ and _____.
