These speed limit and reserved parking signs are on E. 14th St. near College Ave. in Tempe, Arizona.

The speed limit and reserved parking signs say...

the numbers are: 25 1 8 8 the math is: sqrt(8 + 8) + 1 = sqrt(25) rs42Eval: 25 + 1 + 8 + 8 = 42 * 42 is the "Answer to Life, the Universe, and Everything" rsPhiEval: (1 + sqrt(sqrt(25))) / sqrt(sqrt(8 + 8)) = Phi * Phi is the golden ratio and it approximates 1.61803399 more math: 25^(8 - 8) = 1 more math: cuberoot(8) + cuberoot(8) + 1 = sqrt(25) * cuberoot(8) = 2 [2 * 2 * 2 = 8] more math: cuberoot(8 * 8) + 1 = sqrt(5) * cuberoot(64) = 4 [4 * 4 * 4 = 64] more math: 8 / defactorial(25 - 1) = cuberoot(8) fooish math: 1^25 * 8 = 8 more fooish math: 1^25 = (8 - 8)!
