Quick Start Up Instructions

To ensure compatibility with your computer's Operating System, please see the instructions below. (Note: The keyboard is not compatible with an iPad or iPhone. The iOS virtual version of the ArithmeType math keyboard is available on the App Store).

Of course, first carefully remove the keyboard from the shipping box and packaging; then, remove the keyboard from the carrying case.

STEP 1.  Attach the cord.



Plug the USB connector into your laptop or desktop computer. If additional USB ports are needed, USB multi-port devices (splitters, extenders) are available online.

If you’re using a computer without a USB-A port (i.e., a Mac Operating System), a female USB-A to male USB- C adapter will be necessary.


STEP 2. Select the correct operating system (OS) for Chrome/Linux, Mac, or Windows.







Turn the keyboard over and note the label with arrows pointing to the 3 different OS. Using a slim tool such as a pencil or pen, push the small button inside the hole closest to the desired OS. This will light up the OS that matches your computer in the adjacent hole. The keyboard will keep your selection unless a code update is performed. This hidden system is created to prevent inadvertent OS switching during use or transfers.


Chromebook/Linux             press the corresponding button for CHROME/LINUX. That’s it! You’re ready to type.


Macintosh/Apple             press the corresponding button for MAC. Please click the Mac Installer button                                 and follow the steps to help your computer identify the keyboard and enable Unicode Hex Input. Just follow the few onscreen prompts, and then you’re set!


Microsoft Windows 10 or newer (note: older versions not supported)            press the corresponding button for WINDOWS. Next, download the free WinCompose app                            (Please note, if this app download is blocked by your school district account, it can be downloaded from an alternate non-school account onto the computer or downloaded onto a removable USB drive and then uploaded to the student’s computer).

STEP 3. Simply open the compatible document editor or website, and then you can start typing math!

(Note: If your keyboard does not start typing characters immediately wait 5 seconds and try again. If no characters appear, simply unplug and re-plug the keyboard and start typing again. Also, you may want to double check that you selected the correct Operating System on the backside of the keyboard. For additional troubleshooting, please see the Full Keyboard Operation Manual.)
