Install a Graphing Calculator Emulator

The first steps is to install an app called an emulator. There are emulators for a lot of devices (including your favorite childhood video game consoles, be it a Nintendo or a Sega). This specific one will allow you to run a virtual copy of a graphics calculator on your computer.

Head over to the Calculator Emulator website, and download the version which corresponds to your system (Windows, Mac or Android).

Once downloaded, install it on your computer. For a Mac, the install takes two steps:

  1. Double click on the downloaded ZIP archive to uncompress it.
  2. Drag and drop the uncompressed app file into your Applications folder.
NOTE: when you try to run the Emulator for the first time, you may receive a warning that the app is not recognized by Apple. Go to System Preferences > Security > General and click on Open Anyway to bypass the unnecessary warning

Download the Calculator ROM

The next step is to download the ROM, the virtual copy of the device. A ROM (Read-Only Memory file) is a package, much like a firmware which contains all the files needed to emulate the device. Here you can download the ROM for a popular graphics calculator used in math and science classes.

Click on the ROM file to download it. It’s best to keep this file in a good location so you can find it easily in the future.

  3. Choose the ROM file you just downloaded it.
