TempeHiker drove Herb Mumford's car 9.8 miles round-trip to document the Pi street corner. Although the Pi street corner was in Tempe, he parked Herb's car on a neighborhood street in Mesa and walked to the corner of University and Price. Herb's car gets 26.7 miles per gallon and the price for the cheapest unleaded gas was $2.959; therefore, it cost TempeHiker $1.09 to document the Pi street corner in Tempe.

9.8 mi / 26.7 mpg * $2.959 = $1.0859530 $1.0859530 rounded to nearest penny is $1.09This no dumping sign was found next to where TempeHiker parked the car. TempeHiker found an identical "no dumping sign" earlier in the year that became No Dumping at the Center of the Arts in Tempe, Arizona.

This speed hump warning sign was found across the street from where TempeHiker parked Herb's car. No math was found, but there would have been some two-number math if the 20mph was 40mph. During January of 2006, TempeHiker found similar speed hump warning signs in the Tempe's Maple Ash neighborhood that had a couple more numbers to work with.

These road signs were found while walking along westbound E. University to the Pi street corner. During May of 2005, TempeHiker found similar road signs on eastbound E. Baseline Road in Tempe. { Loop 101 Signs on E. Baseline Road in Tempe, Arizona}

The Pi street corner had a litter problem that included numerous litter/spam signs. This litter/spam sign might become a BAB.

the numbers are: 50 89 50 800 853 8458 [exercise] 50 signs for $89 is $______ per sign. [exercise] Record the mean, median, mode for the numbers. primefactorization(800 ) = 2^5 * 5^2 primefactorization(853 ) = 853 primefactorization(8458) = 2 * 4229 8458 - 853 = 7605 primefactorization(7605) = 3^2 * 5 * 13^2TempeHiker found this litter/spam sign somewhat humorous.

the numbers are: 602 251 3131 primefactorization(602 ) = 2 * 7 * 43 primefactorization(251 ) = 251 primefactorization(3131) = 31 * 101
