What Is Discrete Math: Definitions and Scope
Understand what Discrete Math is and why it matters.
Discrete Math is best understood through its purpose: what problem does it solve, or what need does it address? Rather than starting with a textbook definition, think about when and why people encounter Discrete Math in real life. Understanding the "why" first makes the technical details much easier to grasp. The simplest test of understanding: can you explain it in one sentence to someone who's never heard of it?
