TI-84 Plus

This was my first time buying anything used off of Amazon but I needed this calculator and wanted to save money. It came in really good condition, & is definitely worth paying for since it’s literally a steal compared to $100. You do have to put in 4 AAA batteries so just be aware of that. You can tell it’s obviously not BRAND NEW but it’s close enough & gets the job done so that’s all that matters.

Great purchase! Works perfectly as intended!

Good and helpful

Just what I needed for my college class

This graphic calculator is very practical in function, with clear and intuitive graphing. It can meet the basic needs of calculation and drawing. The interface is also relatively simple and easy to get started with. However, sometimes the loading is a bit slow. If it could be further optimized, the experience would be even better. Overall, it's quite good and worth recommending!

Bought this for my daughter in high school and she is still using in college. Excellent quality, battery life, and durability.

Arrived early and is perfect for college math algebra, calculus and engineering classes! Screen isn’t led, but it’s bright enough for use in well lit environment. This calculator is very reliable and comes with pre-installed apps that teach you different math skills and is able to solve equations with missing variables. It is a bigger calculator, but worth it! Only comes in one color black, grey and white which is okay, but it also came with 4 triple A batteries and the usb cord.

This calculator is hands-down the best I have ever had the honor of using. While the TI-84 Plus may not have as much space or as many pre-loaded Apps as the TI-84 Plus Silver Edition, the TI-84 Plus offers everything a high school (possibly some college) math student needs in order to successfully learn and solve mathematics material. The TI-84 Plus comes loaded with several Apps that will make things even more convenient, such as a Probability Simulator and Cabri Jr., a great geometry app. Student looking to upgrade from the TI-83 Plus will find comfort in the fact that the TI-84 Plus is 2.5x faster and has 3x the memory than the TI-83 Plus. The TI-84 Plus is also extremely easy to hook up to your computer to transfer new Apps and updates to it using the USB port and the included USB cable. The TI-84 Plus will be a great investment for any student's education. I didn't want to purchase such a high cost calculator when there are much cheaper work arounds. However, for kids in school, college or taking college tests like SAT and ACT--this calculator is allowed to be used (as is the model below it. So, i bit the dust and purchased it. It works great. It is the standard used in schools so my daughter learned how to use and and can get help on it. The biggest thing is that most of the kids have these and many look alike so you need to mark it well to show it is yours and reduce the chance of theft. this of course isn't TI's fault--but it is good to know. The ti 84+ (this model) has mathprint (stacked fractions and symbols) and a USB cable. TI-83 doesn't have this. Also, i understand that this is faster than the 83. The silver edition os TI 84+ has spreadsheets and SAT/ACT test prep included. That may make it worth the increased price, but I didn't know that until I had already purchased this one. The Memory ROM/RAM between the models are: 160K/24K on TI83 480K/24K on TI84 Plus 1.5 MB/24K on TI 84 + Silver addition (again making the silver addition probably the better value)

Very good & useful product.

Just what I needed for school. Functioning and in good state. I was happily surprised to the notice that batteries are included. Exactly as pictured above.

Item arrived on time in excellent condition. Thank you.

Bought this calculator for my daughter when she started high school. I honestly feel that she wouldn’t have even been able to complete her math class without this calculator. Battery life has been excellent. The display is good. Overall a durable calculator that I feel with last the 3 years of high school .

De lo mejor en calculadoras científicas y de los más completo. Hace todo tipo de funciones y ecuaciones así como la representación de gráficas. Mu rápida y super fiable. Defectos, es un poco grande, no es de bolsillo Lo mejor, te dura para siempre.
