## ✨ Key Features
- **Scientific Functions**: Trigonometry (sin/cos/tan), logarithms, exponents, roots
- **Memory Operations**: Store/recall values, incremental adjustments
- **History Tracking**: Last 10 operations with timestamps
- **User-Friendly Interface**: Color-coded output, angle mode switching
- **Error Handling**: Robust input validation and error messages

## 🛠️ Installation

🌟 Special Features

• Color-coded feedback: Instant visual status indicators
• Last-result reuse: Automatic previous value retention
• Unit conversion: Degrees/radians toggle
• Command history: Access previous calculations with hist

📌 Pro Tip: Use blank input (press Enter) to reuse previous result in calculations!
