Definition
An axiom is a self-evident truth or a statement accepted as true without proof. Think of it as a basic rule in a game that everyone agrees on. It's a foundational principle that serves as a starting point for reasoning. Unlike a theorem, you don't need to prove an axiom; it's just assumed to be true. Axioms provide a solid base for building logical arguments and systems. For example, in math, 'a thing is equal to itself' is an axiom.
