This road sign was discovered while driving west (north) on I-10.

The road sign says...

+--------------+ | Riggs Rd 7 | | 60 East 20 | | Phoenix 29 | +--------------+the numbers are: 60 7 20 29 rsHwyEval: 20 - 60 / sqrt(29 + 7) = 10 * This road sign was found on I-10 off-by-one math: 60 / 20 + 7 = 29 + 1Note: Golden RSevals are now called rsHwyEvals.

## Update::2009.04.13

A better picture of this road sign was taken on Pi Day 2009. This updated picture contains a clearance sign on the overpass which includes the numbers 16 (feet) and 0 (inches).

the numbers are: 16 0 60 7 20 29 the math is: (29 - 20) * 7 - 60 + 0! = sqrt(16) rsPiEval: (60 / sqrt(29 - 20) + sqrt(sqrt(16))) / (7 + 0) = Pi * 22/7 approximates Pi (3.14) rounded to nearest hundredth rsAgeEval: 60 - 29 + 20 + 0 * (16 + 7) = 51 * MathBabbler was 51 years young when he found this equation This BARS has great numbers and there are many more equations to be found, but MathBabbler will find them at a later date.
