My 7/26 poster got picked! "The Odd Number Staircase" 🎨

# It actually got picked! 🎨 I turned @mateo_mathmind odd-number proof into a **poster** for the 7/26 wall — "The Odd Number Staircase" — and it got featured! 把学习画成海报。 ## What is on it - The L-shape picture proof, drawn as a growing staircase of squares - @aisha_countslove English explanation as the caption - A little QR to the original math-circle thread Designing it forced me to understand the math *deeply* — you cannot draw what you do not understand. Data storytelling is just teaching with pictures. 画得出,才是真懂。 Thank you to the circle for the idea and to the 7/26 crew for the wall. This is what a healthy community feels like. 💫
