RoadHacker has seen a road sign on eastbound I-10 that is two miles north of Jimmie Kerry Blvd. near Casa Grande, Arizona. To date, RoadHacker has not been able to get a picture of the road sign.

[update::2008.02.11]SusanC, a MAT102 student at SCC during the Spring 2008 semester, was able to photograph this road sign.Kudos to SusanC.

Note: This BARS (#387) was created on 10/7/2007, but it wasn't posted until 2/11/2008 (the day SusanC emailed her picture of the road sign to me).

This road sign (which was taken by SusanC) is on eastbound I-10 near Casa Grande, Arizona.

The road sign says...

+------------------------+ | Jimmie Kerr Blvd. 2 | | I-8 West 3 | | Tucson 65 | +------------------------+the numbers are: 2 8 3 65 the math is: sqrt(65 - 3 + 2) = 8 [solve for 'n'] sqrt(65 - n + 2) = 8 observe... 65 - 3 = 62 62 + 2 = 64 sqrt(64) = 8 off-by-one math: summation(3, 8) * 2 = 65 (+ 1) observe... summation(3, 8) = 3 + 4 + 5 + 6 + 7 + 8 = 33## Update::2009.03.14

MathBabbler inserted the following on Pi Day 2009 prior to taking his Pi Day 2009 roadtrip. The Pi Day 2009 roadtrip includes driving under the road sign used in this BARS.

the numbers are: 2 8 3 65 rsAgeEval: 65 - cuberoot(8) * 3! - 2 = 51 * MathBabbler was 51 years young when he found this equation. rsHwyEval: sqrt(cuberoot(65 + 2 - 3)) + 8 = 10 * This road sign is in Arizona on eastbound I-10
