This road sign in on northbound Vicksburg Road just north of I-10 in Arizona.

The road sign says...

+-----------------+ | Jct US-60 6 | | Jct AZ-72 8 | | Parker 54 | +-----------------+the numbers are: 60 6 72 8 54 the math is: 6 * (72 - 54 - 8) = 60 more math: sqrt((60 - 54) * sqrt(72 / 8)!) = 6 observe... 60 - 54 = 6 72 / 8 = 9 sqrt(9) = 3 3! = 6 6 * 6 = 36 sqrt(36) = 6 rsAgeEval: 54 - sqrt(72 / 8) * log(60 / 6) = 51 * RoadHacker was 51 years young when he found this sign.## Update::2009.01.23 -- Exercises

`[solve for 'n']`

n * (72 - 54 - 8) = 60`[solve for 'n']`

6 * (72 - n - 8) = 60`[solve for 'log(60 / 6)']`

54 - sqrt(72 / 8) * log(60 / 6) = 51- No or Yes:
`is a factor of`

6`.`

54- No or Yes:
`is a multiple of`

54`.`

RoadHacker drove past this road sign on the morning of Pi Day 2010.

the numbers are: 60 6 72 8 54 rsPiEval: 60 * (54 / 6 / (sqrt(72 /8))) degrees = Pi radians * Special rsPiEval because this road sign was seen on Pi Day 2010. rs42Eval: 54 - sqrt((60 + 72 + 6 * cuberoot(8))) = 42 * 42 is the "Answer to Life, the Universe, and Everything" rsStateEval: 54 - ((72 - 60) / (8 - 6)) = 48 * Arizona was the 48th state admitted to the Union. rsAgeEval: 54 - (8 + 6 - (72 - 60)) = 52 * RoadHacker was 52 years young on Pi Day 2010. rsAgeEval: 54 - cuberoot((72 + 8) / (60 / 6)) = 52 * MathBabbler was 52 years young when he found this equation.
