The road sign says...

+--------------------------+ | McKellips Rd 1 | | McDowell Rd 2 1/4 | | Recker Rd 4 | +--------------------------+the numbers are: 1 (2 1/4) 4) the math is: avg(1, sqrt(4)) = sqrt(2 1/4) observe... sqrt(4) = 2 avg(1, 2) = 1.5 = sqrt(2 1/4) more math: sqrt(2 1/4) - 1 = reciprocal(sqrt(4)) observe... sqrt(2 1/4) = sqrt(9/4) = sqrt(9)/sqrt(4) = 3/2 = 1.5 1.5 - 1 = 0.5 sqrt(4) = 2 reciprocal(2) = 1/2 = 0.5 more math: sqrt(2 1/4) - 1 = sqrt(reciprocal(4)) observe... reciprocal(4) = 1/4 sqrt(1/4) = sqrt(1)/sqrt(4) = 1/2 = 0.5
