These road signs were found approaching the Broadway curve on eastbound I-10 in Tempe, Arizona.

The road signs say...

+----------+ +---------+ +---------------+ +--------------+ | 60 East | | 10 East | | Exit 155 | | Exit 154 | | 1/4 Mile | | Tucson | | Baseline Rd | | 60 East | +----------+ +---------+ | Guadalupe | | Mesa - Globe | | 1/2 Mile | +--------------+ +---------------+ the numbers are: 60 (1/4) 10 155 (1/2) 154 60 the math is: (((155 - 154) / (1/4)) + (60 / 60)) / (1/2) = 10## BABbit

This BARS (Basic Arithmetic Road Sign) was the 961st BAB (Basic Arithmetic Bit). 961 is a square number (i.e. 31^2). This BARS was the 199th BAB created during the Spring 2007 session and it is BARS number 249. Note: 199 is prime, but 249 is not (3 x 83).

The picture used in this BARS was taken on 27 April 2007 while GDT was driving home from downtown Phoenix after attending a math related P-20 "alignment" meeting.
