Polynomial-Time Word Problem for HNN Extensions of Free Groups
A new study shows the word problem for HNN extensions of free groups with equal finite‑index subgroups is solvable in polynomial time, using a bounded rewriting system. getnews.me/polynomial-time-word-pro... #hnnextension #wordproblem
#Teachers, if you ever need a #math #WordProblem for your #LessonPlan, this one might wake your students up.
Here at #CEC2025 and @danielle-lariviere.bsky.social presented on #wordproblem #schemas found in state test items! Half of the schema problems found on test items are the equal groups schema!
Last update on @ReadingLeagueKS Elevating Literacy Conference! @nataliepatton85
led a GREAT session on #wordproblem schema instruction. We practiced identifying schemas and setting up equations! Teachers check out piratemathequationquest.org for more resources on teaching schemas!
