You know those viral fb posts that reduce to order of operations quibbling? Please deploy this associahedron-based interactive viewer in order to subvert those threads with interesting mathematics: kyleormsby.github.io/parse-explor... 🧮

ꭓle Ormsby 𓆙@motivickyle.bsky.social · 2d ago

Resolving ambiguity in order of operations is easy: simply enumerate all possible parsings of a given expression, compute each value, and then average. E.g., for 9-3-3÷3, ((9−3)−3)÷3 = 1 (9−(3−3))÷3 = 3 (9−3)−(3÷3) = 5 9−(3−(3÷3)) = 7 9−((3−3)÷3) = 9 so 9-3-3÷3 = (1+3+5+7+9)/5 = 5. Voilà! 🧮

Easiest way to get $5 out of me at the airport is to be some dude playing piano and sneaking this into the set. (I was not the only person around me obviously thinking at least "where have I heard this before") youtu.be/QS0pGbf0XbU

> I presume the proof is correct (there's supposedly a Lean formalization, after all), but it will take me some time to digest it. This is why math is still important in a world where AI can provide nontrivial proofs. There's far more to care about with most interesting questions than yes/no.

Life was busy so I didn't get a chance to look, but I guess now the cat's out of the bag so I probably should opine a bit. I presume the proof is correct (there's supposedly a Lean formalization, after all), but it will take me some time to digest it.

Blue Prince is a fun game, but someone needs to teach the dev about vacuous logic.

Person: how do you get through them all? God: I made them countable man, what else do you want from me?

[Alt-text] A red-haired person in a green shirt talks with God : "God, do you have mathematical proofs that humans cannot fathom?" God: "No? All proofs work the same way." The person: "They do?" God: "Like the proof that √2 is irrational. You just check all the rationals. None of them are √2."

Hey for those who attended our #PreTeXtGang workshops earlier this year and use pretext.plus, @davidwfarmer.bsky.social @oscarlevin.com and @clontz.org have improved the functionality many orders of magnitude over what it was!

We just published the 2026 version of the TBIL Resource Library at tbil.org. These free and open activity books and exercise banks support instructors in implementing Team-Based Inquiry Learning (or other active learning) in Precalculus, Calculus (I and II), and Linear Algebra. tbil.org/library/

I am excited to share that the print version of our "Linear Algebra for Team-Based Inquiry Learning" activity book is now available for preorder from 619 Wreath! www.619wreath.com/store/p56/Li...

I'll go there: pretext.plus now has a better mobile interface than Overleaf.

And now thanks to the beauty of open source / open access, you can view the electronic version of Linear Algebra for @tbil.org online for free: tbil.org/library/ Also includes materials for Precalculus and Calculus!

just found a website that has "Share on X" (not Twitter) and "Share on Google+" buttons, but no "Share on BlueSky" lol

Well, there is a min here. #MathSky #deltarune

I don't know how the For You feed manages to catch that I'm a sucker for #deltarune Forgotten Man memes but who am I to argue with progress?

You can now create projects from templates in PreTeXt.plus! Do you have a useful #PreTeXtGang starter document (on PreTeXt.Plus or GitHub) that would be useful for others to iterate on? Share it here or DM me and we may add it to the list!

A more charitable characterization from a friend: "Steven, whenever I hear you explain the rules to a game, I'm reminded how much you must love teaching."

Mansplained dice pair sum distributions to my wife (she's played Catan lol what was I thinking) and was appropriately punished by losing to her in Can't Stop.

Is it time to start writing your course materials? Want to make them accessible? We are hosting a few free workshops in the next weeks to help you do just that with PreTeXt. And using PreTeXt.Plus means nothing to install and no GitHub required. Info here: pretext.plus/announcement...

PreTeXt.Plus | Writing Accessible Course Materials with PreTeXt: workshops in July & August 2026 | Office Hours at MAA MathFest

To help our colleagues adopt PreTeXt to meet this need (whether via the PreTeXt.Plus app, or a local install of PreTeXt's free and open source software), we're excited to offer several virtual workshops this July and August.

Indeed, it did not hurt to ask! Here's the Prefigure code to make the image. Note the shading doesn't show up here because of the aforementioned bug, but will if you download it.
