## Updated::2009.05.11

This BARS was updated because of new functions and rsEvals that have been added to the BARS system.

the numbers are: 17 10 17 10 rsAgeEval: cuberoot(17 + 10) * 17 * log(10) = 51 * MathBabbler was 51 years young when he found this equation rsAgeEval: 17 + 17 * log(10 * 10) = 51 * MathBabbler was 51 years young when he found this equation off-by-one rs42Eval: 17 + 17 + 10 - log(10) = 42 + 1 * 42 is the "Answer to Life, the Universe, and Everything" number system rsPiEval: (17_{16}- log(10)) / (17 - 10) = Pi * 22/7 approximates Pi (3.14) rounded to nearest hundredth fooish math: sqrt(17^(log(10) + log(10)) = 17 off-by-one math: sqrt(17 - log(10)) - cuberoot(17 + 10) = 1
