What counts as "knowing" something in math if no person can follow the proof? @OpenAI says an internal model produced 372 results on open math problems, many verified in Lean. If proof becomes "passes a machine checker," what changes in math class? #iteachmath #MathEd

3 questions I'm sitting with: 1. Should students learn to verify AI reasoning, not just produce their own? 2. Does "show your work" still mean the same thing? 3. How do we keep understanding at the center, not just correctness?

3/ The reveal: it's the Nobel Peace Prize, 1901–2026 🕊️ 🟡 107 years a prize was awarded ⚪ 19 years with no prize 9 of the 19 empty years fall during the two World Wars. The 2026 prize went to Navi Pillay, South African jurist, for her work for peace and international law.

4/ Your turn 🧮 Which decade had the most empty years? What percent of years went without a prize? Reply with your answer AND how you figured it out. Bonus: what would you want your students to notice first? #iteachmath

We don't always have to rely on "two negatives make a positive" when subtracting a negative.

The @Brewers sweep the Dogers 4-0 and clinched a spot in the World Series last night. If the chances of winning were a coin flip (50/50), how likely is a 4–0 sweep? Let me know in the comments. Solution posted later. #WorldSeries #Brewers @MLB
