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).

Start Up Instructions
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.
On the arithmetype.com website, go to the Keyboard Operation Manual & Downloads tab. 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  from the Keyboard Operation Manual & Downloads tab of the home page.
(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.)

Operating Instructions 
Most of the characters will display on the computer screen just as they appear on the key.  Just push the key. It’s that easy. 

Special keys on the keyboard:
* Two options keys (examples): 
   
As you can see, on these keys there are two different options listed--one option is large font and the other option is smaller font.  A simple keypress will activate the large font option to display on the screen.  To activate the smaller font option, first press the 2nd key  and then press the desired key. Following that, it will then be reset to the original option. For example, if you press the key with bold u delta, you get bold u. If you press 2nd, then bold u delta, you get delta.


* Start Google Docs EQ key:

This key, featured in purple, only works in Google Docs on the first press and creates a shortcut to opening the equation editor.  The 2nd option of this key will open the equation editor in Word or OneNote. 

Once the Google Docs EQ button is pressed, after a slight pause, a box will appear on the screen with a flashing cursor inside.  (Note: Google Docs must be in standard menu mode for this key to function correctly. This means that File, Edit, View, Insert, etc. are visible on the menu bar). Once the Google Docs Equation Editor is activated, it allows the user to create:


* Limits, Sums, and Integrals with spatial formatting:


In Google Docs Equation Editor: Press the 2nd key followed by the desired key. The symbol will appear with a flashing cursor below it. Enter a number, letter, or symbol then press enter. The cursor will move to the next position.  Press enter again to enter additional characters. Press enter to exit the equation editor. 

In Word/OneNote Equation Editor: 
For limits, press “lim” key. Then on the main math keyboard, evoke the subscript EQ key by pressing 2nd, then subscript. If more than one digit is being typed to go below the limit, put the terms into parentheses. Then press space to see the formatting appear and this moves the cursor to the original line of typing. Enter the next term and press the arrow key to the right to advance out of that entry. Press enter to exit the equation editor.

For Sums, press the 2nd key, then ?. Then on the main math keyboard, evoke the subscript EQ key by pressing 2nd, then subscript. If more than one digit is being typed to go below the limit, put the terms into parentheses. To enter the term on top, press ^ and the term. Then press space to see the formatting appear and this moves the cursor to the original line of typing. Enter the next term and press the arrow key to the right to advance out of that entry. Press enter to exit the equation editor. 
Note: The full enhanced formatting is better displayed when typing the equation on a new line rather than on the current line of typing. The equation will appear in the center of the line when it is in optimal form.

For integrals, press the ? or ? key. Then on the main math keyboard, evoke the subscript EQ key by pressing 2nd, then subscript. If more than one digit is being typed to go below the limit, put the terms into parentheses. To enter the term on top, press ^ and the term. Then press space to see the formatting appear and this moves the cursor to the original line of typing. Enter the next term and press the arrow key to the right to advance out of that entry. Press enter to exit the equation editor. 
Note: The full enhanced formatting is better displayed when typing the equation on a new line rather than on the current line of typing. The equation will appear in the center of the line when it is in optimal form.


* Formatted Fractions
	 
partial differential y/partial differential x              dy/dx

       In Google Docs Equation Editor, press 2nd key, then parital differential y/partial differential x or dy/dx key. Press enter to leave the Equation Editor.
       
	In Word/OneNote Equation Editor, press parital differential y/parital differential x or dy/dx key. Press enter to leave the Equation Editor.

* Vector Symbol
  

In Google Docs Equation Editor, press 2nd key, then ? key. The vector will elevate over the characters. Enter the desired characters below the vector. Press enter to move out from under the vector symbol. Press enter to leave the Equation Editor. 

In Word/OneNote Equation Editor, first enter the characters to put beneath the vector. If more than one character, put them in parentheses. Next press, the 2nd key, then ?, then press spacebar. The vector will now be over the characters. Press enter to leave the Equation Editor.


* Vertical line with a over b  GD EQ or | Tall line


This denotes the limit of a function and typically written at the end of the function. 

In Google Docs Equation Editor, press this key and a tall bar will appear with the cursor now below the line of text at the lower limit. Type the value for the lower limit. Press Enter, and the cursor will go to the upper limit value. Type the upper limit value and press enter. Press enter again to leave the Equation Editor.

In Word/OneNote Equation Editor, Then on the main math keyboard, evoke the subscript EQ key by pressing 2nd, then subscript. If more than one digit is being typed to go below the limit, put the terms into parentheses. To enter the term on top, press ^ and the term. Then press space to see the formatting appear and this moves the cursor to the original line of typing. Press enter to exit the equation editor. 

In MathQuill websites such as ArithmeType, Desmos, DeltaMath, and more, press the 2nd key, then the ? key. To type the lower limit, on the main math keyboard evoke the subscript EQ key by pressing 2nd, then subscript. Type the entry and press tab to move the cursor back to the baseline. Next, to type the upper limit on top, press ^ and type the term. Then press tab and this moves the cursor to the original line of typing. 


* Boldface Type: 


Pictured in pink, this turns on/off boldface in any document. As stated, this function only works in documents such as Google Docs, Word, OneNote, TextEdit, etc. This is useful for typed vector notation which is typically boldfaced.


* Boldface Unicode characters (example): 
 

Boldface characters i,j,k,u,v are common vectors used in multivariable calculus. Again, these are most consistently displayed on a document but can often be used on websites, extensions, PDF editors, etc. It may be font specific, meaning it will only display in certain fonts. We recommend using fonts such as Cambria Math, Times New Roman, Latin Modern, Asana Math, XITS Math. 


       
Code Update
Rarely, the code for the keyboard may need to be updated to conform with any changes that a particular OS may require. Perform the following steps below.
1. Put the keyboard into reset mode. Choose one of the two methods below. 
a. Hold the top left key down (Start GD EQ)   while plugging the USB into your laptop. Keep holding the key a few seconds and then release. A chime may be heard. The keyboard is now in reset mode. 
b. Hold down the Code Update button on the back of the keyboard while plugging in the keyboard. Keep holding the button a few seconds and then release. A chime may be heard. The keyboard is now in reset mode.

2. A new drive called RP1-RP2 will open.



3. Next, on the ArithmeType home page click the UPDATE button to download the new file.

4. Now open the files icon on your computer and find the downloads file. Double Click to open it.



5. The ArithmeType download will be displayed there. Drag and drop the file into the RP1-RP2 drive. A chime may be heard.



6. The keyboard has now been updated. Be sure to reselect the correct OS on the back of the keyboard since its previous selection was erased during the reset.

Screen Readers
The ArithmeType Math Keyboard is most compatible with NVDA and JAWS. For optimal use, screen readers should be set to recognize Unicode characters. There will be variability in different screen reader’s interpretation of the multikey commands, such as Start Google Docs EQ. This may instead be read at “e” since the command is alt, i, e. Please utilize Google Chrome for the best experience using screen readers with the ArithmeType Math Keyboard. See Reference table below for a verbal description of the keyboard. Any non-spoken characters can be added using the software for the screen reader.
