Randy Weiss, full of excitement, brings his first constant sign to Road Sign Math. At the same time, he continues to extend Massachusetts lead to 20 signs! The next closest state is Pennsylvania with 15.

This is simply a different go-around at the most commong pi derivation, 22 over 7.

{44 \over {21 - 7}} \approx 3.142857 \approx 3.14 \approx \pi

This sign is in the town of Lexington on I-95 northbound. The GPS coordinates are approximately N42 27 12.5 W71 15 24.4. See sign on map!

    Oh, dear. Big mistake: the three bars are a definition sign, i.e. they mean "is defined as, being exactly and always equal to." The correct sign in this case is the approximation sign, or "squiggly equals."

    Mister Moy,

    You are very right! How embarassing! I can’t believe nobody has mentioned that before. I’ve fixed it in all the appropriate constant signs. Thanks!
