We discuss important meta-issues regarding definitions and specification in mathematics. We also introduce the idea that mathematical definitions, expressions, formulas or theorems may support a variety of possible interpretations.

Examples use our previous definitions from elementary geometry. This video belongs to Wildberger's MathFoundations series, which sets out a coherent and logical framework for modern mathematics.
