Need something simpler than a TI-84 Plus CE?
If your class or exam only allows a basic non-graphing scientific calculator, try our free TI-30XS calculator instead — same no-download, keyboard-friendly experience, without graphing.
Why not just use the old calculator sites?
Typical calculator sites
- Dense, dated layouts with no visual hierarchy
- Light mode only
- Mouse-only interaction
- No saved history or variables
TI-84 Calculator
- Clean, spacious, premium interface
- Dark mode first, with light & system support
- Fully keyboard-operable
- Persistent history, variables, and Ans
Frequently asked questions
Is this a real TI-84, or an emulator?
It's an original web app inspired by the TI-84 Plus CE's layout and workflow — not a ROM emulator and not affiliated with Texas Instruments. It runs entirely in your browser.
Is it free to use?
Yes. The calculator is free, with no account or install required.
Does it work on mobile?
Yes — the layout adapts to a touch-friendly single-column view on phones and tablets.
Can I use my keyboard instead of clicking?
Yes. Every operation has a keyboard shortcut, including Enter to evaluate and arrow keys to move between buttons.
Is my history saved if I close the tab?
Yes — your history, stored variables, and last answer are saved locally in your browser and restored next time you visit.
Can I graph functions on this calculator?
Yes — switch to Graph mode for function, parametric, polar, and sequence graphing with pan, zoom, and trace. Tools mode adds matrices, statistics, distributions, hypothesis tests, an equation solver, and finance calculations.
What's the difference between the TI-84, TI-84 Plus, and TI-84 Plus CE?
They're successive generations of the same Texas Instruments calculator family — the TI-84 Plus CE is the newest, with a color screen and rechargeable battery, while the original TI-84 and TI-84 Plus use monochrome displays and AAA batteries. This calculator is modeled on the TI-84 Plus CE's layout and keeps the same function set, so anything you learn here carries over to any TI-84 model.
