Casio FX-991 CW (Italian Model) Scientific Calculator, 540 Functions and Natural Display

Perfect for GCSE maths

Works fine no issues quite durable and never have to replace the battery.

It works very well, no complaints about it. I use it everyday in class and I absolutely love it

The best scientific calculator we think, ideal for modern education ,a must!

Bought for my son for his A level maths. Would recommend this product. Great value for money too

I was a bit disturbed by the price, but now that I'm using it I'd say it is worth it. It is lightweight, and seems qualitative if handled well. It came with guide on how to use it, so I will figure it out

son needed the up dated version for 6th form he is happy with it doing the job

My son wanted this for his year 12. It's wot he needed

This calculator is everything I needed as an upgrade from my 1980's Texas Instruments calculator. While my TI calculator was good for basic stuff, it could not do algebraic equations.

Funciona bien

version casio 991ex améliorée. Ecran avec contrastes simultanés gris clair gris foncé et noir rendant le tableur plus facile à lire. Les fonctions sont mieux regroupées et rendent l'ensemble plus ergonomique. Plus de 570 fonctions mathématiques et un solveur très efficace. Par contre manque les calculs modulaires. Le couvercle n'est pas coulissant mais vient se clipser prenant l'ensemble moins épais. Ensemble robuste et très bien fini. Mode d'emploi sur téléphone . Le logiciel gratuit ClassPad Math sur téléphone permet de voir l'allure des résultats des courbes en scannant le QR sur la calculatrice Pour l'instant très satisfait de mon achat.

The Casio fx-991CW quickly became one of my favorite calculators. It’s fast, reliable, and covers everything from basic math to advanced functions. The interface is clean and intuitive, and the build quality feels solid. Ideal for students, engineers, and everyday problem solvers.

You can define your own function, and use it efficiently. And the basic functions are also good.
