I have purchased several of these calculators. They are absolutely excellent! I’ve purchased these for my three older children who are in high school and college. This calculator is requested in all upper level math classes. This calculator will stand the test of time. It is very durable. The battery life is excellent. It lasted several school years without needing to be replaced. The numbers on the calculator are easy to read and the screen is bright. The accuracy is 100%. The children have never gotten an answer wrong when putting in an equation correctly on this calculator. It is quick to compute any answer. There is no lag. I highly recommend this calculator as it will last for years and years!

Ottima calcolatrice grafica che svolge esercizi di algebra lineare (matrici, determinanti ecc), statistica (media, standard deviation...) e analisi ( derivate, integrali definiti, studio di funzione, asintoti, intersezione con gli assi, punti di flesso, punti di massimo e minimo ecc). C'è da dire che con le derivate e gli integrali la calcolatrice mostra soltanto il risultato finale e non tutti i passaggi (non è step by step), peró comunque è utile per vedere se il proprio risultato è corretto e coincide con quello della calcolatrice. Non è cas. Non si puó collegarla al computer. Utile per le classi quinte superiori e all'università. Ho imparato ad usarla guardando molteplici tutorial su youtube in inglese, comunque su internet si dovrebbero trovare facilmente le istruzioni per l'uso in italiano sotto forma di pdf. Ottimo acquisto, consigliata. Arrivata in tempo per il mio esame di analisi.

Needed this for my daughter for grade 10. Amazon was cheapest and it came quick too. So far so good.

I bought this calculator for my daughter who is doing her A level maths as it is one that is allowed in the exam itself .... it saves a lot of time plotting by hand graphs. She found it easy to use too.

Me llegó muy rápido y en excelentes condiciones.

La calculatrice était en bon état extérieurement seulement, je l'ai reçu cassé, j'ai eu beau changé de pile elle ne fonctionnait pas !!
