What this tool does
Familiar TI-84 Keypad
The layout matches the physical device, so the muscle memory you built in class transfers straight over.
Function, Polar & Parametric
Switch between y = f(x), r = f(θ) and x(t)/y(t) from the toolbar, exactly as the handheld's mode key does.
Table of Values
Generate the table for any expression and read the points a question asks for without plotting by hand.
Step-by-Step Solver
Send an equation to the step solver to see the working — quadratics, linear equations, systems and derivatives.
Frequently Asked Questions
Is this an official Texas Instruments calculator?
No. It is an independent, third-party tool inspired by the TI-84 Plus™ layout. TI-84 Plus™ is a trademark of Texas Instruments Incorporated, which does not endorse, sponsor or authorise this site.
Is it really free?
Yes. No account, no download, no trial. Open the page and start calculating.
Can I use it on the SAT or ACT?
No online calculator is permitted during official exams. Use this page to learn the keypad layout and rehearse the keystrokes before exam day, then bring an approved handheld into the room.
Does it work on a Chromebook?
Yes. It runs entirely in the browser with nothing to install, which matters on managed school devices where downloads are blocked.
Can I save my work?
Your graphs stay in your browser session. Nothing is uploaded to a server and no account is required.
