This road sign is on the Hawaiian Island of Kauai.

The road sign says...

+-------------------+ | Airport 2 mi | | 3 km | | Lihue 2 mi | | 3 km | +-------------------+the numbers are: 2 3 2 3 the math is: 3! + 2 = 2^3 [solve for 3!] 2^3 = 3! + 2## Update::2008.11.14

MathBabbler noticed that mileage-to-kilometer ratios are not correct on this road sign.

observe... 1 mi = 1.609344 km [exercise] fix the road sign +--------------------------+ | Airport 2 mi | | ________ km | [round to nearest hundredth] | Lihue 2 mi | | ________ km | [round to nearest hundredth] +--------------------------+## Update::2008.11.14

There is a squared-numbered 25 mph speed limit sign beyond this road sign.

the numbers are: 2 3 2 3 25 the math is: (2 + 3) * (2 + 3) = 25 more math: log(sqrt(25 * 2 * 2)) * 3 = 3 more math: (sqrt(3! * 3!) - sqrt(25)) * 2 = 2 rsPhiEval: (3 / 3 + sqrt(sqrt(25))) / sqrt(2 + 2) = Phi * Phi is the golden ratio and it approximates 1.61803399 rsPiEval: (25 - 3) / (2 + 2 + 3) = Pi * 22/7 approximates Pi (3.14) rounded to nearest hundredth rsAgeEval: 25 * 2 - 3 + 3 + 2 / 2 = 51 * RoadHacker found this sign at the age of 51 years young. rs42Eval: 25 * 2 * (3 - 2) - 2^3 = 42 * 42 is the "Answer to Life, the Universe, and Everything"
