No Parking, Math OK

Frank Solensky continues his blitzkrieg of mathematically significant roadsigns with a new entrant to Road Sign Math. This no parking sign contains numbers that many would not even notice.



The math here combines times and days of the week, and even brings a square function for fun.

$$3^2 - 1 = 8$$

This sign is found on Meacham Rd. near Campbell Park in Somerville, Massachusetts.
