Road Sign Math

Randy Weiss continues his string of new state introductions this time bringing New Hampshire’s first mathematically significant roadsign! The sign is a bit less than exciting, but it is still valid. It is curious that the sign was modified at some point to remove two positions, but what would they have been. It would be rare for a sign to start with 0. Also, why in the world do the numbers go from right to left. This sign may in fact hold great mysteries.

This may be the simplest math possible in Road Sign Math.

1 + 2 = 3

This sign is found along I-89 southbound where I-89 ends and joins I-93. The GPS coordinates are approximately N43 05 50.2 W71 28 33.4. See sign on map!

Ed.: There was an error in the Sharon sign stating it was Mr. Weiss’s 5th new state. In fact, it was his 6th! New Hampshire is now his 7th (Montana, Rhose Island, South Dakota, Utah, Vermont and Wyoming being the others), giving him a clear lead in the most states introduced to Road Sign Math!
