H.B. Elkins is on a terror and brings us yet another mathematically significant roadsign, this time from Ohio.

This is the most common approximation of pi, but the great thing is how direct this winner makes it.

22 \div 7 \approx \pi

This sign was found on in Steubenville, Ohio just across the Ohio River from Weirton, West Virginia. See sign on map!

Frank Kaszar, another first-timer to our wonderful game, brings us another new state with a mathematically significant roadsign. Ohio makes it’s debut on Road Sign Math with this great sign. The city of Ravenna has a striking name, however, it seems it’s history is rather plain for such a great name.


Picture taken at night.

Some wonderful, and not terribly obvious, math in this sign.

( 14 + 6 ) \times 4 = 80

This sign was found on eastbound I-480 between Cleveland and Hudson in Ohio. The GPS coordinates are approximately N41.29263 W81.42386. See sign on map!

Ed.: Ohio is the 32nd US state to make it on Road Sign Math! Only 18 more until we have a blackout!
