This is how I'd envision a scene from Number Lore, if it took place in Bren's version of the Russian Alphabet Lore. It's almost the same, but У is in the group, due to У looking like a Y, and the scene referencing the slope-intercept formula, "y = mx + b". But Ю is still here due to her having Y's role. Also, it was hard to do Х’s shocked/surprised expression, so I kept his original angry expression here. @bren319, you can remix this project to fix his expression if you want.
