This road sign is on Parker Dam Road across the Colorado River from Parker, Arizona, in California.

The road sign says...

+---------------------------------------------------+ | Straight Ahead To | | --------------------------------------------- | | River Shore 4 1/2 | Big Bend 12 | | River Land 5 | Californian 12 1/2 | | Emerald Cove 6 1/2 | River Lodge 14 | | Rio 7 | River Lodge Too 14 1/2 | | Rite Sport 8 | Sunshine Resort 14 3/4 | | Windmill Park 8 1/2 | Black Meadow 25 | | Echo Lodge 11 | Havasu Palms 29 | +---------------------------------------------------+RoadHacker first found this sign during December of 2006 and a BARS was created. As a result of finding the sign a second time, 2006 BARS was updated to include a

`rsAgeEval=48`

and a`rs42Eval`

.RoadHacker photographed the sign a 2nd time on 27 May 2008. This BARS was created containing the following road sign evaluations:

`rsAgeEval=50`

,`rsPiEval`

and`rsPhiEval`

.the numbers are: 4.5, 5, 6.5, 7, 8, 8.5, 11, 12, 12.5, 14, 14.5, 14.75, 25, 29 River Lodge Too? A = ((11 - 8) * (29 - 25)) / (14.75 - 14.5) = 48 B = (12.5 - 8.5) - (6.5 - 4.5) + (7 - 5) - (14 - 12) = 2 rsAgeEval: A + B = 50 * RoadHacker took this picture on his last day being 50 years young. A = (6.5 - 4.5) * ((12.5 - 8.5) * (14.75 - 14.5)) = 2 B = 12 + 8 - 14 + sqrt(29 + 7) - sqrt(5 * sqrt(25)) = 7 rsPiEval: (A * 11) / B = 22 / 7 = Pi (3.14) * 22/7 approximates Pi (3.14) rounded to nearest hundredth C = sqrt(29 + 7) / (14 - 11)! = 1 D = sqrt(sqrt(12 + 8 + sqrt(sqrt(25) * 5))) = sqrt(5) rsPhiEval: (C + D) / A = (1 + sqrt(5)) / 2 = Phi (1.16803399) * Phi is the golden ratio and it approximates 1.61803399## Related BARS

## Updated::2009.05.01

The following math was discovered on 1 May 2009 after this BARS was selected as one of the BARS of the Week for Week #15 of the spring 2009 semester.

the numbers are: 4.5, 5, 6.5, 7, 8, 8.5, 11, 12, 12.5, 14, 14.5, 14.75, 25, 29 A = 4.75 - 14.5) = 1/4 B = 6.5 - 4.5 = 2 C = 12.5 - 8.5 = 4 the numbers become: 5 7 8 11 12 14 25 29 1/4 2 4 rsAgeEval: (7 - 5)*(11 - 8)*(14 - 12)*(29 - 25) + 2 + 4 * 1/4 = 51 * MathBabbler was 51 years young when he found this equation
