What I Like Casio PRIZM FX-CG50
- Color-rich display and 3D graphing: The bright 65,000-color LCD makes complex graphs clear and engaging. When plotting 3D surfaces like spheres or cones, it feels almost like seeing math come alive.
- Python integration: I personally enjoyed experimenting with MicroPython directly on the calculator. It’s great for learning coding basics without needing a computer.
- User-friendly layout: Casio’s icon-based menu and smooth navigation make it easy to move between algebra, geometry, and statistics. I never felt lost, even when switching between modes.
- Exam-approved reliability: It’s allowed on most major U.S. standardized tests something that saves you the hassle of checking compatibility.
- Long battery life: Four AAA batteries lasted months in my testing, even with frequent graphing and Python use.
What Could Be Better
- No rechargeable battery: I wish Casio offered a rechargeable option. While AAA batteries last long, USB charging would make it more convenient.
- Slight learning curve with 3D graphing: The first time I plotted multiple surfaces, the setup menu felt a bit complex. A more guided interface would help beginners.
- Plastic casing: It’s durable enough, but for $100+, a more premium material or rubberized grip would enhance the overall feel.
