These parking signs are on N. Farmer Ave. in Tempe, Arizona.

The parking signs say...

+------------+ | NO Parking | | 1am to ?am | | Tow Away | +------------+ +-----------------+ | 1 HR Parking | | 8am to 6pm | | Mon thru Fri | | except holidays | +-----------------+the ? is probably 8, but it could be a 6 if ? is 8, the numbers are: 1 8 1 8 6 and the math is: 6 - sqrt(8 + 8) - 1 = 1 observe... 8 + 8 = 16 sqrt(16) = 4 6 - 4 - 1= (6 - 4) - 1 = 2 - 1 = 1 if ? is 6, the numbers are: 1 6 1 8 6 and the math is: sqrt((sqrt(1 + 8) + sqrt(1 + 8)) * 6) = 6 observe... 1 + 8 = 9 sqrt(9) = 3 3 + 3 = 6 6 * 6 = 36 sqrt(36) = 6 [exercise] Find more math especially when ? is a 6.
