Create a new interactive playground for practicing rules of inference under Discrete Math > Foundations. The playground will feature a three-column layout for premises, a workspace with parallel lines for derivations, and a column for relevant inference rules. Users can drag and drop elements, apply rules, and receive validation for their steps. The initial example will be based on the provided screenshot.
Adds the "Knights and Knaves - I" interactive to the Foundations section. The interactive features a central arena and five external boxes for statements. Dragging statements into the arena turns them green, and incompatible statements turn the arena red.
Implement a ternary number representation interactive, similar to the binary one, with powers of three and toggles for 0, 1, or 2 copies of each number, up to the seventh power of 3. Include a random number generator up to 3280.
Create green-screen versions of interactives, accessible via "/gs-dark" and "/gs-lite" paths. Hide layout elements, set green background, and adjust text/element colors for optimal green screen use.
