This street sign was found on Rio Salado Parkway in Tempe, Arizona.

The street sign says...

+------------------+ | W 1st St 100 -> | +------------------+ the numbers are: 1 100 the math is: log(sqrt(100)) = 1 observe... sqrt(100) = 10 (10 x 10 = 10^{2}100) log(10) = 1 (10 ^ 1 = 10^{1}= 10)This street sign cannot be submitted to RoadSignMath.com because it uses the

`log()`

function. RSM discontinued allowing`log()`

during April of 2006.
