LaTeX counters control all automatic numbering in your document. This guide covers how to create custom counters, modify existing ones, and implement sophisticated numbering schemes for any document element.
Key concept: LaTeX uses counters to track numbers for sections, figures, tables, equations, and more. Understanding counters lets you create custom numbering schemes and control how elements are numbered throughout your document.Related topics: Page numbering | Cross-referencing | Document structure

Best Practices

Counter management guidelines:
  1. Plan your numbering scheme - Design consistent hierarchy before implementation
  2. Use descriptive counter names - problem is better than prob or p
  3. Reset appropriately - Child counters should reset when parent increments
  4. Document your system - Comment complex counter relationships
  5. Test thoroughly - Check numbering across document sections
  6. Consider references - Ensure counter formats work well with \ref{}
