+---------------+ | Jct 87 6 | | Chandler 13 | | Mesa 20 | +---------------+the numbers are: 87 6 13 26 only off-by-one math was discovered on 2006.04.29 rs42Eval math found on 2008.10.17: sqrt(87 - 6) + 13 + 20 = 42 * 42 is the "Answer to Life, the Universe, and Everything" original off-by-one math... observe... 22/7 approximates Pi; therefore, equivalent fractions of 22/7 also approximates Pi; 88/28 is equivalent to 22/7 88 / 28 = 3.14285714 approximates Pi (3.14159265) 87 / (20 + 13 - 6) = 3.22222222 the numerator 87 is off-by-one (needs to be 88) the denominator 27 is off-by-one (needs to be 28) 3.2222 is 2.57% greater than 3.1416 ...another off-by-one equation... sqrt(87 + 13) / 20 = 6 - 1Note: AZ Hwy-587 is a prime numbered highway.
