1. Download and launch the app, then pick your preferred layout, angle mode, and theme in Settings.
2. Enter numbers first, press operations after; tap Enter to push values to the stack and use stack keys like Swap or Roll to manage entries.
3. Use key groups for common tasks: scientific functions for trig, logs, and powers; financial functions for cash flows or time value calculations; store and recall with memory registers.

5. Open the tape to review your calculation history, copy or share results as text, and clear or archive when finished.
