How to Use

This guide walks you through the online TI-84 Plus CE calculator. If you have used a physical TI-84 before, the steps will feel familiar.

1. 1

   Open the calculator

   Go to the Calculator page or use the embedded calculator on the homepage. No sign-up or download is required.

2. 2

   Enter expressions

   Click the on-screen buttons just like a physical TI-84. Use keyboard focus on the calculator area for accessibility support.

3. 3

   Graph a function

   Press Y= to enter functions, then GRAPH to plot. Use TRACE and ZOOM for analysis, the same workflow as the handheld calculator.

4. 4

   Adjust the size

   Use the + and - zoom buttons above the calculator to scale it for your screen. Your zoom preference is saved automatically.

5. 5

   Use on mobile

   Open the full-screen Calculator page on phones for the best layout. Pinch-zoom your browser if you need extra magnification.
