A free online graphing calculator with the TI-84 Plus CE key layout, menus and syntax, for students who use one.

TI-84 Plus CE Alternative: Free Online Graphing Calculator: If you use a TI-84 Plus CE at school, the key positions and familiar labels help you practise the same sequences here. Use normalcdf and invNorm from 2nd → vars, enter data in stat → EDIT, or plot functions from y=. The home screen keeps the expression on the left and the result on the right. Use the arrows to browse history, then enter to paste an earlier expression. Use alpha to enter a variable once, or 2nd → alpha to toggle A-lock. The calculator has its own calculation engine and its own appearance. Apps, programs, Python and other graph modes are unavailable. Numerical calculations and simplified menus can differ from your handheld. This page is for study outside proctored exams. Runs 100% locally in your browser with zero server file uploads.

Frequently asked questions

Is this a TI-84?

TI-84 Plus CE and MathPrint are trademarks of Texas Instruments Incorporated. TOEA is not affiliated with or endorsed by Texas Instruments. This is an independent calculator with a compatible key layout; it does not run TI software.

Can I use it on an exam?

No. Online calculators are not allowed in proctored exams. Check what your exam allows. The SAT provides its own built-in calculator, which is a different product.

Does it match my calculator’s results?

Common arithmetic and distribution calculations use compatible syntax and display ten significant digits in Float mode. Numerical methods, supported functions and menus can differ. Degree or Radian and Fix settings also affect the displayed answer. Check important work on the calculator your course requires.

Does my data leave the browser?

No. Expressions, variables, lists, matrices, functions, settings and history are calculated and saved in your browser. Reset calculator clears that saved state.
