MathCue: Math Recall

MathCue is a recall aid that helps you quickly bring back math concepts you've already learned.
It doesn't teach from scratch — it gives you the cue that makes "Oh, right!" happen.

■ See concepts as a graph
- All of middle‑school math (Korean curriculum, grades 7–9) as a prerequisite → follow‑up graph.
- Narrow down by domain (Number & Operations, Algebra, Functions, Geometry, Probability & Statistics) → unit → concept.
- Prefer a plain view? Switch to a list sorted by grade or A–Z.

■ Recall cards
- Each concept in one line: definition + key formulas + "recall it when…" triggers + a worked example.
- Hop to related (prerequisite / follow‑up) concepts.

■ How to use
- Flip through right before an exam to refresh your memory.
- Follow the links from one concept to the next to grasp the whole flow.
