TI-83 Plus

It works great. I needed one desperately for classes and I couldn’t afford a brand new one. It gets the job done. I highly recommend because you can’t beat the price.

Tried and true graphing calculator — still widely used in schools✔️ Proven design that hasn’t changed much in years✔️ Standard for high school and college math courses✔️ Reliable and consistent performance✔️ Easy to use once familiar✔️ Widely accepted for exams and courseworkThis calculator has been around for a long time, and it still feels very similar to when I used it back in the 90s.I bought it for my wife’s schooling, and it’s exactly what you’d expect. It’s a staple in high school and college math, and it continues to be widely used and accepted.It may not be flashy, but it’s reliable and gets the job done without any issues.

Funciona bien a pesar de ser usada

I haven’t used one of these in 25 years. While still generally the same Ti graphing calculator I had back in college waaaaay long ago, the TI-83 has some more bells and whistles. Unfortunately, the stats class I was taking required me to have a few more functions than this model had , so I had to run out to Walmart before they closed and buy the TI-84 plus for the exam. I will be trying to resell my Ti83 to reclaim some of my money, but in all honesty, the Ti 83 works fine, it just didn’t have some of the advanced features I needed for my class. You can’t go wrong with the Ti 83 or 84.Edit Update: June 2024 —> I am so happy! I was able to gift a single mom with 3 kids my unused Ti 83. Her oldest son is in STEM classes and is apparently very gifted in mathematics and is starting 8th grade this coming year. He wants to be an “engineer or a mathematician” when he grows up. I’m so pleased that it went to a good home where it will get years of good use. It really is better to give than receive! 😊

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.

This calculator was required by my son's college. He's been using it all year with no problems at all. It was new in the package when we received. It does the job and has held up well!

Helped me pass statistics! Good for the price. Color is fine it’s easy to use

The TI-83 Plus is an older model of programmable scientific calculator. This is the 4th one we each use. I am an electrical engineer, and my wife is working in medical nutrition at the clinical level.We each both need a practical type of calculator for being able to quickly solve equations we each commonly use. Her applications are in the bio-medical field, and mine is with solving electrical engineering problems. We each have over 20 different formulas written in to our calculator. We also keep a calculator on hand as a spare in case one of these fail.I was able to write the software coding based on required formulas and save it to this model of calculator. We have the original detailed instruction books for this calculator giving examples of the coding and process about how to write software in to this model type. It is fairly involved, but works out very well. This calculator model is a very advanced type for its size and gets the equations easily and quickly solved. It is much more convenient for portability than using Excel or some other type of math software on a laptop.We have the TI calculator management software installed in our computers, and can back up the calculator's programs to the computer's data drive. We have been using this model of calculator since it came out and being used to it and very proficient with this model, makes our preference is to not change the model. There is a newer equivalent version with advancements for the display and etc.We have been using this model of calculator sometimes every day since 1998 when they came out. Over the years with use they have eventually failed. Sometimes the calculator may be dropped, and over time with use there are wear factors involved. With near daily use and for at least an hour or more per day we are getting about 4 to 6 years of use from each calculator. This is terrific.The memory battery lasts about 3 years average in these. This is not difficult to change. The main batteries last about 6 months to 1 year with daily use. There is a procedure to allow the memory battery to be changed without losing the programs stored in calculator.With the data transfer cable that comes with the calculator it is possible to back up the calculator's programming and variables to another one like it. There is also the silver USB type interconnect cable that allows this calculator model to be backed up to a computer using the TI calculator management software.

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.

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 !!
