Reliable Class Icon!
The Casio fx-991ES Plus 2nd Edition is a perfect blend of "old school" dependability and modern functionality. It maintains the legendary Casio quality that has made it a staple in classrooms and engineering offices for years. What I love: Natural Textbook Display: This is a total game-changer. It displays fractions, roots, and exponents exactly as they appear in textbooks, making complex equations much easier to input and understand. Incredible Functionality: With 417 functions, it handles everything from basic trigonometry and statistics to advanced calculus, matrix calculations, and equation solving with ease. Bulletproof Build: The redesigned body feels solid and durable, featuring wear-resistant printing and a secure slide-on hard case that stands up to daily use in a backpack. Dual Power Reliability: The combination of solar and battery power (LR44) means it’s always ready to go, whether you're in a brightly lit lab or a dimly lit lecture hall. Intuitive Layout: The color-coded keypad and ergonomic design make it easy to navigate, striking a great balance between high-end features and simple, no-fuss operation. Whether you’re a student or a pro, this calculator is a reliable "math companion" that offers exceptional performance and value. It's a five-star workhorse that gets the job done every time.

Solar Wow!
My kid says it works great! The price wasn't too bad either. My child was able to find and use all the functions a bit easier than other scientific calculators before. The box did come in a bit beat up but all good so far.
