This road sign is on eastbound I-10 in downtown Tucson, Arizona.

The road sign says...

+--------------------+ | 6th Ave | | 4th Ave 1/4 | | Benson Hwy | | Park Ave 3/4 | +--------------------+the numbers are: 6 4 (1/4) (3/4) the math is: 6 / (3/4) * sqrt(1/4) = 4 observe... 6 / (3/4) = 6 * (4/3) = 24/3 = 8 sqrt(1/4) = sqrt(1) / sqrt(4) = 1/2 8 * 1/2 = 8/2 = 4 more math: log(6 + 4) - (1/4) = (3/4) observe... log(6 + 4) = log(10) = 1 1 - (1/4) = (3/4) more math: 6 / sqrt(4) * (1/4) = (3/4) observe... sqrt(4) = 2 6 / 2 = 3 3 * 1/4 = 3/4 [exercise] solve for 'n': 6 / (n/4) * sqrt(1/4) = 4 [exercise] solve for 'n': 6 / n * (1/4) = (3/4)
