Developer Insight: Why Tape Calculators Matter
From a technical standpoint, this calculator implements an Event-Driven State Machine. Each row represents a state entry; when you edit an entry, the application re-validates the mathematical string through a sandboxed arithmetic parser. This ensures 100% accuracy while maintaining a reactive UI that updates derived totals (like Sum or Average) in real-time.
