MathBabbler visited his mom, dad, and sister during winter break 2015. He drove from his sister's house in Plainfield to his parent's old folks home in Shorewood via Illinois Hwy-59 numerous times. Each time he noticed a road sign that he never got a chance to get a picture of.

The road sign says...

+-------------------+ | Shorewood 5 | | I-55 6 | +-------------------+the numbers are: 5 55 6 the math is: 6! % 55 = 5 * 6! = 720; 720 % 55 = 13 R 5 rsPivot5math: 55 / 5 = 5 + 6 * Note: First time usage ofrsPivotNmath. rs42Eval: sqrt(55 - 6)! / 5! = 42 * 42 is the "Answer to Life, the Universe, and Everything" spf(n) = the sum of the prime factors of n * domain: n must be a composite number * 55 is composite; spf(55) = 5+11 = 16 BARSfunc rsCardinalityEval: sqrt(spf(55)) + 5 - 6 = 3 BARSfunc rsCardinalityEval: cuberoot(5 + 6 + spf(55)) = 3 * There are three numbers in this road sign.
