This road sign is on northbound US Hwy-61 in Missouri.

The road sign says...

+---------------------+ | Wayland 8 | | St. Patrick 5 | | Gregory Landing 4 | +---------------------+This sign was discovered during June of 2006, but no math was found until October of 2008. During the early part of 2008, evaluations such as the rs42Eval, rsHwyEval, rsAgeEval were added to BARS. MathBabbler saw this sign while he watching the screen saver scoll through pictures and that prompted he to re-examine the road sign for math.

the numbers are: 8 5 4 rs42Eval: 8 * 5 + sqrt(4) = 42 * 42 is the "Answer to Life, the Universe, and Everything" base-2 math: (5 * sqrt(4))_{2}= cuberoot(8) base-4 math: (5 * 4)_{4}= 8 base-5 math: (8 + sqrt(4))_{5}= 5 base-8 math: (5 * sqrt(4))_{8}= 8 off-by-one math: 8 - 5 = 4 - 1 off-by-one math: 8 / sqrt(4) = 5 - 1 off-by-one math: (4! / 8)! = 5 + 1 off-by-one math: sqrt(8 * sqrt(4)) = 5 - 1 off-by-one math: sqrt(5 + 4) = cuberoot(8) + 1 rsAgeEval: 8 * 5 + 4 + dup(5) = 49 * RoadHacker was 49 years young when he found this sign.
