Overview
The TI-84 Plus is Texas Instruments' long-standing graphing calculator for algebra through early college coursework, running on four AAA batteries with a silver oxide backup cell. It comes with a USB connectivity cable, a slide case and Cabri Jr. geometry software preloaded.
This is the model most math teachers already know, which matters more than raw processing power once a classroom has standardized on it. It predates the CE line's color screen, so graphs render in grayscale on a 320 x 240 pixel display rather than full color.
- 320 x 240 pixel backlit display
- Up to ten graphed functions at once
- Cabri Jr. interactive geometry software preloaded
- USB connectivity cable and slide case included
Who it's for
Best suited to high school algebra, trigonometry and statistics students, and to families who want a calculator a teacher already knows how to walk students through. It is not the newest TI screen technology, so shoppers focused on color graphics should look at the CE instead.
Pros and cons
- Runs on AAA batteries so it never needs a charger
- Cabri Jr. and probability apps preloaded, no downloads needed
- Familiar to most math teachers, easing troubleshooting in class
- Grayscale, lower-resolution screen next to the CE model
- No rechargeable battery included
Performance notes
The unit graphs up to ten functions at once with seven graph styles and fourteen zoom presets, and a split-screen mode lets a student view a graph and its table or equation side by side. An I/O port allows file and program transfer to other TI-84 units, which is how classrooms share calculator-based labs. The apps, including Cabri Jr. and a probability simulator, run locally without needing a phone or computer connection.
