Any model of TI-84 Plus will work for this course. Several options are provided aboveĀ - choose only one! To help you decide, here are the key differences:
- TI-84 Plus: This is the most basic model, but it does everything we need. It has a gray and black standard screen, runs on AAA batteries, and is thicker and heavier than the CE models. It comes with a cable if you buy it new. Fresh batteries will last a long time, and the calculator will let you know when they need to be changed. I recommend this model to people who won't keep track of chargingĀ a calculator, as long as they don't mindĀ theĀ basic screen and the heavier calculator body.
- TI-84 Plus Silver Edition: The same as the TI-84 Plus, with a few extra built-in apps that we won't use anyway.
- TI-84 Plus CE: ThisĀ model has a backlit color screen and a built-in rechargeable battery. It is thinner and lighter than the TI-84 Plus. The data cable it comes with is also the charging cable. This model is better for ease of reading the screen. The more recently manufactured ones (since 2017) also have an extra feature that can be used to safeguard against accidental corruption or deletion of program files. This model is my recommendation, if the added cost is manageable. Keep in mind that you will have to charge it regularly.
- TI-84 Plus CE Python: This model is the same as the TI-84 Plus CE, but with extra programming capability that we won't use in this course anyway. No need to pay extra for this model, but if you want it, go for it.
- Note: Don't get 'TI-84 Evo'. It is not compatible with the programs in this course.

One more note: Some things are entered or displayed differently on the basic model, the CE model, and the CE Python model. These differences are explained in the course lesson videos.
