These highway signs were found near an I-25 entrance ramp located between Colorado Springs and Denver, Colorado.

The highways signs say...

+-------+ +-----------+ +-------+ | North | | CO Hwy-16 | | South | | I-25 | +-----------+ | I-25 | +-------+ +-------+ the numbers are: 25 16 25 off-by-one math: 25 / 25 = sqrt(sqrt(16)) - 1 observe... 25 / 25 = 1 sqrt(16) = 4 sqrt(4) = 2 more off-by-one math: 25 / sqrt(25) = sqrt(16) + 1 observe... sqrt(25) = 5 25 / 5 = 5 sqrt(16) = 4 more off-by-one math: sqrt(25 - 16)! = sqrt(25) + 1 observe... 25 - 16 = 9 sqrt(9) = 3 3! = 3 x 2 x 1 = 6 sqrt(25) = 5
