The airport signs say...

+-----------+ +-------+ | 8 9 | | 5 6 7 | | Left Exit | | | | | | | | v | | v | +-------+ +-----------+ the numbers are: 5 6 7 8 9 the math is: summation(6, 8) - summation(5, 7) = sqrt(9) observe... summation(6, 8) = 6 + 7 + 8 = 21 summation(5, 7) = 5 + 6 + 7 = 18 21 - 18 = 3 sqrt(9) = 3 ...or... 6 / sqrt(sqrt(9 + 7)) + 5 = 8 observe... 9 + 7 = 16 sqrt(16) = 4 sqrt(4) = 2 6 / 2 = 3 3 + 5 = 8RoadHacker says "Thank You" to Fela for the picture.
