This road sign was found two miles east of Lake Pleasant on AZ Hwy-74 in Arizona.

The road sign says...

+--------------------+ | Lake Pleasant 2 | | Jct. U.S. 60 21 | | Wickenburg 30 | +--------------------+the numbers are: 2 21 30 60 the off-by-one math is: sqrt(60 - 30 - 21) = 2 + 1 rsAgeEval: 60 + 21 - 30 - 2 = 49 * MathBabbler was 49 years young when this road sign was found. split_into_squares_sum(60) = { 36, 16, 4, 4 } the numbers become: 2 21 30 36 16 4 4 the math is: (sqrt(30 - 21) * 2 * sqrt(4) * sqrt(4)) / sqrt(16) = sqrt(36)
