Road Sign Math

Randy Weiss continues his quest to put Massachusetts on the top of the hill for mathematically significant roadsigns with the wonderful Quincy sign found just north of Boston. This sign is just so simple and straightforward. Dare I say it? Elegant?

The math in this sign uses the square root operator, one of only a handful of unary operands, to get a 2 into the sign and make the math work..

This sign is found on I-93 southbound just 9 small miles north of ‘Bean Town’ in the Middlesex Fells Reservation. The GPS coordinates are approximately N42 27 17.9 W71 06 10.7. See sign on map!
