With 696 functions and a handy QR code option, you can quickly solve any mathematical challenge, from vector calculations to integrals. The sturdy hard case keeps your calculator safe in your bag on the way to school or the office.
When do you choose this product?
For complex calculations at school and university
This scientific calculator has been specially developed for students and professionals who need to carry out advanced mathematical operations. With 696 functions, you can tackle everything from basic algebra to complex university calculations such as integral and differential calculus. The device is indispensable for exact subjects such as mathematics, physics, chemistry and technical studies.
Why this extensive functionality
The FX-991 DE X offers not only standard calculation functions, but also specialised capabilities such as vector calculation, solving inequalities and prime factorisation. These functions are essential for higher mathematics and technical courses. The spreadsheet function makes it possible to analyse datasets, while the 47 built-in physical constants save time on physics calculations.
Modern tools for efficient working
The QR Code function is a unique feature that helps you share or verify calculations via your smartphone. This makes collaborating and checking results much easier. The recurring decimal fractions function shows exactly how repeating patterns in results arise, which is especially useful in theoretical mathematics.
Practical design with protection
With dimensions of 77 x 165.5 x 11.1 mm, this calculator fits comfortably in your hand and school bag. The included hard case protects the device against bumps and scratches during transport. Please note that this model has been specifically developed for the German, Luxembourgish, Austrian and Swiss markets, which is reflected in the menu structure and documentation.
