These street signs were found on E. 8th Street at its intersection with Dorsey in Tempe, Arizona.

The street signs say...

+---------------------+ | E 8th St 1300 -> | | S Dorsey Ln <- 900 | ----------------------- | STOP SIGN | | 4-way | ----------------------- | No Parking | | within | | 30 ft of | | stop sign | +---------------------+the numbers are: 4 8 30 900 1300 the math is not: ((1300 - 900) / 80))! / 4 = 30 GDT divided 400 by 8 and erroneously got 5. 400 / 8 equals 50, not 5. If only the 8 was an 80, but it's not -- it's an 8. Probably wishful thinking after seeing 4 x 30 is 120. 5! is 120 (5x4x3x2x1) googlecalc... 50! is 3.04140932 x 10^64 (10^63 is one vigintillion) (((1300 - 900) / 8) !) / 4 = 7.6035233 x 10^63Learning that 400 divided by 8 is not 5, we resumed playing with the numbers.

the numbers are: 4 8 30 900 1300 the math is: sqrt(1300 - 900) + 8 + sqrt(4) = 30 observe... 1300 - 900 = 400 sqrt(400) = 20 sqrt(4) = 2## Update::2008.12.10

The last time MathBabbler visited Four Peaks noticed the street signs used in this BARS, but he didn't remember that he had created this BARS. On 10 December 2008, MathBabbler revisited street corner to get a picture and when got to SCC to create the BARS he discovered that he had already created this BARS during December of 2006.

Between December of 2006 and December of 2008, MathBabbler had created a set of road sign evaluations (rsEvals) and found some of those rsEvals were added to this BARS.

the numbers are: 4 8 30 900 1300 rs42Eval: 30 - sqrt(1300 - 900) + 4 * 8 = 42 * 42 is the "Answer to Life, the Universe, and Everything" rsAgeEval: sqrt(1300 / 4 * 8 + sqrt(900) / 30) = 51 * MathBabbler was 51 years young when he updated this BARS. rsAgeEval: 30 + sqrt(1300 - 900) + sqrt(4) / cuberoot(8) = 51 * MathBabbler was 51 years young when he updated this BARS. rsAgeEval: 30 + sqrt(1300 - 900) - sqrt(4) / cuberoot(8) = 49 * MathBabbler was 49 years young when he created this BARS. rsHwyEval: 30 - sqrt(1300 - 900) - 8 / 4 = 8 * These signs were found on 8th Street.
