```   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 - 1
```

Note: AZ Hwy-587 is a prime numbered highway.
