Texas Instruments TI-83 Plus Graphing Calculator, Gray, Standard

Perfect condition!! Works great!!

Great for child school use

My son needed a graphing calculator for his high school math career & this was the school's recommended model. Nice price for a nice calculator that was easy for him to learn and is super easy to read.

I liked it. Works to Me, so I’m happy with it.

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!

I was using a TI-89 which is far superior, BUT, it is not allowed in the math department at my university only the TI-83 Plus, TI-83, and TI-84(including their various releases). The calculator FEELS very basic, however, with a little knowledge you can take the calculator on through Calculus 3 as I understand, I dont believe that it can do derivitives so you'll be writing those out by hand. I purchased "TI-83 Pluss Graphing Calculator for Dummies" And I would say that a book of that nature really is mandatory, its no fun hunting thing down on the calculator itself or within the different tabs, say math for example you may never know that what your looking for is in one of those tabs. The advertisement for this calculator is a little decieving it says you can transfer files to and from your calculator. This is true but you have to purchase a special cord which is essentially a 3.5mm jack(not sure actual size) on one end that you plug into the bottom of the calculator and a USB connection on the other end. You also have to download the software to move the files from the Texas Instruments website. None of this really matters in my opinion because as little as two programs will fill the calculators memory, not worth it. The graphing calculator is well made, seems a little light in the hand but overall construction is solid. Takes 4 AAA batteries and has an auto shutof of 5 minutes. It really is a decently powerful calculator that will get you through your math and is just powerful enough to not let you cheat. I personally have not taken any calculus so I cant vouch for its usefullness but I was told, by many instructors that this was the calculator to buy and would be of the most benifit, for what the department allows, through Calculus 3. To add to what I said earlier about getting a book, the calculator comes with a pamphlet on how to use it, garbage.

Purchased for my grandson for high school! Easy to use and very versatile!

Was marketed as 'Used - Good' but looked brand new when I opened it. Can't beat that.

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 !!
