This example demonstrates an interactive “Squares Memory” quiz: the system shuffles a pool of questions, shows randomly selected items, and lets the learner judge whether each item fits the square-number rule, with immediate feedback and hints. The key mathematical ideas are square numbers and rule-based correctness checking, supported by sequence generation and random sampling for creating practi
