(x, why?) is "a webcomic of math humour, school life and general geekiness". Expect puns. It was created by Chris Burke, a public school math teacher in New York City, and has been publishing since 2007. He also has a blog running in parallel, where people can leave comments.
Since the comic is "Gag A Day", you can jump in anywhere, but there are some characters who frequently reoccur. These include: Anthropomorphic Numbers (like Kitt 10, or Mr. 0 who hosts a show on F(x) News), Shapes (like Trigonometry Jones), and some Human characters (mostly teachers, like Michael Keegan and Kenneth Wayne). More recent updates occur at random, but strips will also usually appear on significant days of the year, such as Christmas and Veteran's Day.

This webcomic provides examples of:
- All Just a Dream: Averted. The substitute character exists beyond that storyline.
- Another Dimension: References to 3D, as well as 1 and 4 end up in a negative dimension.
- Incredibly Lame Pun: For instance, pronouncing xkcd out loud.
- Police Are Useless: Averted. Police generally get the job done, whether the cops are stick figures or even shaped like Keystones.
- Show Within a Show: Mr. Wayne sometimes publishes his own webcomic, Ken-Do!.
- Song Parody: Several, including a big one for The 700th Comic.
- Stick-Figure Comic: Super Stickman was once a Sunday regular.
- Suspiciously Similar Substitute: The substitute teacher, Quinn Jonas. (Funnier when this trope was called 'Jonas Quinn'.)
