/**
 * Calculator Example Class
 *
 * This file demonstrates various types of changes that the diff plugin handles:
 * - Line additions (new methods)
 * - Line deletions (removed code)
 * - Line modifications (changed logic)
 * - Context lines (unchanged surrounding code)
 *
 * Try asking OpenCode to:
 * 1. Add more operations (multiply, divide, power)
 * 2. Add error handling for division by zero
 * 3. Add TypeScript generics for number types
 * 4. Convert to a functional approach
 * 5. Add input validation
