What Is the TI-84 Calculator Online?
The TI-84 Plus CE is one of the most widely used graphing calculators in high school and college math classrooms, and our TI-84 calculator online brings that exact same tool into your web browser. Graph parabolas, solve systems of equations, calculate derivatives, run regressions, work with matrices, and handle trigonometry and logarithms all without installing a separate app.
It's a practical backup when you've left your calculator at home, a handy tool for teachers demonstrating concepts on a projector, and a reliable option for anyone who wants TI-84 accuracy without the upfront cost of new hardware.
How to Use the TI-84 Calculator Online
Getting started takes less than a minute. If you've used a physical TI-84 before, these steps will feel very familiar.
- 1
Open the calculator
Click Open TI-84 above or scroll to the embedded calculator on this page. No sign-up or download required.
- 2
Enter your problem
Use the on-screen keypad to type expressions, just like a handheld TI-84. Solve arithmetic, algebra, and more from the home screen.
- 3
Graph a function
Press Y= to enter one or more equations, then GRAPH to plot them. Use TRACE and ZOOM to explore the graph in detail.
- 4
Run statistics or programs
Open the STAT menu for regressions and data analysis, or the PRGM menu to write and run TI-BASIC code.
- 5
Adjust for your screen
On smaller screens, open the full-screen calculator page and use the zoom controls to resize the display.
Benefits of Using a Free TI-84 Calculator Online
A browser-based TI-84 saves time, money, and hassle. Here's why students and teachers keep coming back to this tool.
Full graphing power
Plot functions, trace curves, find intersections, and analyze equations the same way you would on a physical TI-84 Plus CE.
Works in any browser
No app store, no install, no waiting. Open the page on your laptop, tablet, or phone and start calculating right away.
TI-BASIC programming
Write, edit, tackle complex calculations and run TI-BASIC programs in the same environment your math and science classes use every day.
Completely free
No account, no trial period, no hidden fees. The calculator stays free for students, teachers, and anyone who needs it.
Authentic TI-84 emulator
If you've used a TI-84 in class, every button and menu will feel familiar. This is a true TI-84 Plus CE emulator, not a lookalike. There's almost no learning curve.
Great for remote learning
Left your calculator at school? Working from home? Pull up the online TI-84 on any device with an internet connection.
TI-84 Calculator Online vs. Desmos and Other Free Tools
Desmos is a great free graphing tool, and if you're taking the Digital SAT, it's actually built into the test itself. But Desmos isn't a TI-84 emulator—it doesn't replicate the TI-84 Plus CE's menu structure, TI-BASIC programming, or the exact keystrokes your teacher demonstrates in class.
This TI-84 calculator online is different: it's the real TI-84 Plus CE interface, menus, and math engine, so what you practice here is exactly what you'll see on a physical TI-84 Plus CE—same Y= editor, same STAT menu, same PRGM environment. If your class or exam expects TI-84-specific keystrokes rather than a general-purpose graphing tool, this is the closer match.
Built for Homework, Exam Prep, and Classrooms
Whether you're graphing parabolas in Algebra I, running regressions in AP Statistics, working through related rates in Calculus, or debugging a TI-BASIC program for a computer science elective, this online TI-84 Plus CE gives you the same interface you already know without carrying hardware everywhere.
Parents can help kids with math at the kitchen table. Tutors can share a link instead of lending out a device. Teachers can project the calculator during a lesson so the whole class follows along step by step.
Frequently Asked Questions
Quick answers to common questions about the free online TI-84 Plus CE calculator.
Is this TI-84 calculator online really free?+
Yes. You can use the full TI-84 Plus CE emulator at no cost. There's no account to create and no subscription to worry about.
How is this different from buying a physical TI-84?+
The online version runs the same TI-84 Plus CE software in your browser, so the menus, buttons, and math results match the handheld calculator. The main difference is that you access it through a web page instead of carrying a device.
What's the difference between the TI-84 Plus and TI-84 Plus CE?+
The TI-84 Plus CE is the newer model—it has a full-color screen, a rechargeable battery, and more memory than the original TI-84 Plus, which uses a monochrome display and AAA batteries. This online calculator is based on the TI-84 Plus CE, so it matches the version most schools currently issue.
Is this the same as Desmos?+
No. Desmos is a separate, general-purpose graphing tool with its own interface. This TI-84 calculator online is a dedicated TI-84 Plus CE emulator, so the menus, keystrokes, and TI-BASIC programming match a physical TI-84 exactly—useful if your class or textbook gives instructions in TI-84 terms.
Can I use this TI-84 calculator on my phone?+
Yes. It works on modern phones and tablets. For the best experience on mobile, open the full-screen calculator page and use the built-in zoom buttons to fit the keypad on your screen.
Do I need to download or install anything?+
No. Everything runs inside your web browser. After your first visit, key files are cached locally so the calculator loads faster next time.
What math classes is the TI-84 good for?+
Students use the TI-84 for algebra, geometry, pre-calculus, calculus, statistics, and physics. It handles graphing, equation solving, matrices, trigonometry, and data analysis.
Can I use this on a standardized test?+
Most proctored exams require a physical approved calculator and do not allow browser-based tools. This site is built for homework, practice, and classroom work. Always check your exam's calculator rules before test day.
Does it support TI-BASIC programming?+
Yes. You can create, edit, and run TI-BASIC programs just like on a physical TI-84 Plus CE. This is useful for math projects and learning how calculator programming works.
Is this website affiliated with Texas Instruments?+
No. TI-84 Plus CE is a trademark of Texas Instruments. This is an independent educational site and is not endorsed by TI.
