# Road Sign Math: every sign in full

> Every sign on https://roadsignmath.xyz, newest posted first. The short index is https://roadsignmath.xyz/llms.txt; the same data as JSON is https://roadsignmath.xyz/signs.json.

A way is accepted when the math is true and every number in it is one of the numbers on the sign, each used no more often than the sign shows it. Using every number is encouraged, not required. Anyone can find another way on any sign. There are no points, scores or rankings.

Jamie Thingelstad started the game in 2005 as roadsignmath.com, with signs sent in by other players until 2014. This site and the iPhone app are its new era; the first era’s signs are kept in the archive on Things I’ve built, not here.

Each sign has a page at `/signs/<slug>` and each player at `/players/<handle>`. Most places are approximate: the pin sits on the town the post or the sign names. `found_on` is the day in the finder’s own time; other times are UTC.

- Caption: All things have a beginning and the quest for mathematically significant road signs starts with this very sign.

This sign is on I-94 East as you drive toward the Twin Cities. Each time I would drive by it when returning from North Dakota I would see the math before I would see the cities on the sign.

"I wonder how many road signs have mathematical relationships like that?"

And thus Road Sign Math was born.

Given the importance of this sign, I pulled over and got a selfie with the sign itself.
