## BAB Milestone

This was the 400th BARS (Basic Arithmetic Road Sign). It is also BAB #1461. As of 16 March 2008, approximately 27.4% of all BABs are BARS.

## Update::2008.10.31

The following math was discovered on 31 October 2008 after this BARS was selected as one of the BARS of the Week for Week #11 of the fall 2008 semester.

the numbers are: 2 41 41 39 44 47 45 the math is: (47 + 45 - 41 - 41) / (44 - 39) = 2 rsPhiEval: (2 - 41 / 41 + sqrt(44 - 39)) / (47 - 45) = Phi * Phi is the golden ratio and it approximates 1.61803399 rsHwyEval: 41 + 41 - 2 - (44 - 39) - (47 - 45) = 73 * This sign was found on AZ Hwy-73. rsAgeEval: (47 - 39) * (2 * (44 - 41)) + sqrt(45 - 41) = 50 * RoadHacker was 50 years young when he found this sign. more math: sqrt(sqrt(44 + 39 - (47 - 45))) - 41 / 41 = 2 more math: (44 - 41)! - (41 - 39) - (47 - 45) = 2 more math: (47 - 41)! / (44 - 39)! - (45 - 41) = 2## Update::2009.03.08

This BARS was selected to be one of the BARS of the Week for week #8 of the spring 2009 semester.

the numbers are: 2 41 41 39 44 47 45 rs42Eval: (41 + 41) / 2 + log((44 - 39) * (47 - 45)) = 42 * 42 is the "Answer to Life, the Universe, and Everything" rsAgeEval: (41 + 41) / 2 + (44 - 39) * (47 - 45) = 51 * MathBabbler was 51 years young when he found this equation. more math: (cuberoot(47 - 39) + (45 - 41)) / 2 = 44 - 41 [solve for 'n'] (cuberoot(47 - n) + (45 - 41)) / 2 = 44 - 41
