Montague Flipside

David Slauenwhite gives us a quick 1-2 with the backside of Montague Pi also showing a great mathematical relationship. This is the 2nd time we've seen this mathematical somersault, the other being Cambridge Math and Cambridge Math Backside from Randy Weiss.

$$63 + 47 = (15 - 5) \times 11$$

This sign is at the northern terminus of Route 47 at Route 63 in Massachusetts.
