RoadHacker has driven past a set of road signs on northbound I-294 in Chicago, Illinois, numerous times but he has never gotten a picture. RoadHacker drove past the road signs on Memorial Day 2009 (May 25th) and he remembered the numbers in the road signs.

The road signs said...

+-----------------------+ | I-294 I-290 | | IL Hwy-20 IL Hwy-64 | +-----------------------+the numbers are: 294 290 20 64 the math is: sqrt(20 - cuberoot(64)) + 290 = 294 more math: 294 % 290 = 64 % 20 rs42Eval: 64 - 20 - sqrt(294 - 290) = 42 * 42 is the "Answer to Life, the Universe, and Everything" rsStateEval: 20 + cuberoot(64) / (294 - 290) = 21 * Illinois was the 21st state admitted to the Union rsAgeEval: 20 + sqrt(64) + (294 - 290)! = 52 * MathBabbler was 52 years young when he posted this BARS off-by-one rsAgeEval: 20 + sqrt(64) + (294 - 290)! = 51 + 1 * RoadHacker was 51 years young when he last saw these signs more math: sqrt(sqrt(20 - cuberoot(64))) = gcf(290, 294) more math: 294 - 290 = gcf(20, 64)Note: This BARS was posted on MathBabbler's 52nd birthday.
