# Mission: Combinatorics

## Why
Learn combinatorics in a structured way through short lessons that make counting problems, arrangements, selections, and casework feel intuitive instead of intimidating.

## Success looks like
- Solve foundational counting problems without guessing formulas blindly.
- Recognize when to use permutations, combinations, complementary counting, or casework.
- Build enough confidence to tackle progressively harder discrete math and probability problems.

## Constraints
- Lessons should be short and mobile-friendly.
- The learning flow should work well across multiple sessions.
- Examples should stay practical and readable instead of feeling too abstract too early.

## Out of scope
- Heavy formal proof-writing as the first focus.
- Advanced combinatorics before the basics are solid.
