Why this site exists

Most US math classes ask students to use a TI-84 graphing calculator. Not every student owns one, and many leave theirs at school or lose it before a test. We built this site so the same keys and menus are available on any laptop, Chromebook or phone, for free.

The guides on the site follow the exact button presses used on a real TI-84, so a student can practise here and then use the physical calculator in class or in an exam.

How the calculator works

  • Written from scratch. The math engine, graphing, statistics and matrix tools are our own code. We do not use Texas Instruments software, ROM files or emulator images.
  • Runs in your browser. Nothing is installed. Your lists, functions and settings are saved in your browser’s local storage, not on our servers.
  • Checked against known answers. Before each update we test the calculator against results from textbooks and standard tables, such as normal distribution values and regression outputs.
  • Always improving. We add features students ask for. If you find a wrong answer, please tell us and we will fix it.
