It doesn't bury the reader in dense notation. It uses clear language to bridge the gap between "common sense" and formal mathematics.
Most mathematics textbooks follow a "Theorem-Proof-Example" structure. While logical, it often hides the intuition behind why a concept exists. A problem-oriented approach flips this script:
Many universities offer free PDFs of "Inquiry-Based Learning" (IBL) notes for Graph Theory, which are entirely problem-driven. Conclusion
