Click "Open Calculator" above. It loads directly in your browser — nothing to install. Works on Chrome, Safari, Firefox, and Edge.
Basic math, graphing, statistics, matrices — the same menus you'd find on the physical TI-84 are all there.
Press Enter and the result appears instantly. No lag, no server round-trips. Everything runs on your device.
Key Features
Each feature below mirrors the real calculator's layout. If you already know the TI-84, you'll feel right at home.
Type your functions here and graph them. Supports multiple functions plotted at once. autocad 2006
Cube roots, fractions, absolute values, and probability functions — all in one menu.
Enter data lists and run standard deviation, variance, regression, and Z-tests. You can use special control codes to insert
Set exact X and Y ranges to control which part of the graph is visible.
Access all secondary functions printed above each key, exactly like the physical calculator. This drastically reduced the size of block libraries
Type variable names and letters — useful for storing values and working with programs.

You can use special control codes to insert symbols and formatting into single-line text: : Diameter symbol ( ∅the empty set %%D : Degree symbol ( ∘raised to the composed with power %%P : Plus/Minus symbol ( ±plus or minus %%U : Toggles underlining on/off %%O : Toggles overlining on/off %%% : Percentage symbol (%) Troubleshooting Tips
Perhaps the most transformative feature of the 2006 release was the introduction of . Before this version, blocks were static entities—predefined symbols that had to be exploded or redefined if they needed a slight modification, such as changing a door's swing or a chair's width. Dynamic Blocks introduced "parameters" and "actions," allowing a single block to represent multiple configurations. This drastically reduced the size of block libraries and empowered designers to make real-time adjustments without re-drawing components, marking a significant leap in design efficiency and productivity .
