It is now possible, at no extra cost, to embed accessible math equations within Microsoft Office (Word, PowerPoint, Excel), Google Docs, Mac Office Software (Pages, Key Note), and D2L using MathType add-in. Creating equations using MathType, puts them into the accessible format MathML that can render directly in web browsers. When equations are in MathML they can be read correctly by a screen reader such as Jaws, Read Aloud, and Voice Over. The equations can also then be converted to Nemeth Braille on a Braille Display that is typically connected to the computer via USB or Bluetooth.

What is Accessible Math?
Accessible math is a format with the following characteristics and benefits:
One of the best ways to increase your productivity is to take advantage of shortcut keys in Microsoft Word. Word includes shortcuts for most common functions right out of the box, though you can.
- From the Apple menu, click System Preferences Keyboard Shortcuts App Shortcuts. Click the + sign to add a keyboard shortcut. In the Application menu, click the Office for Mac app ( Microsoft Word, Microsoft PowerPoint, Microsoft OneNote, Microsoft Outlook) you want to create keyboard a shortcut for.
- If you don't find a keyboard shortcut here that meets your needs, you can create a custom keyboard shortcut. For instructions, go to Create a custom keyboard shortcut for Office for Mac. Many of the shortcuts that use the Ctrl key on a Windows keyboard also work with the Control key in PowerPoint for macOS. However, not all do.
- MathType is the intelligent mathematical equation editor that works with any word processor, desktop publishing, presentation, and Web-authoring software to insert typeset-quality equations into.
- The math is visible in a notation that a computer generates from fonts in its character set. It is not an image file. Unfortunately, many current applications use image files for displaying equations. While it is possible to add 'Alt text' to these images, this does not provide access to manipulate, edit or solve it.
- A screen reader can read the equation and sequence through it character by character.
- A Braille display can present it in standard Nemeth or UEB Braille.
- The user can independently edit and solve it.
- The user can create math in the same format. At MSU, this will enable students to give their work back to the professor.
- The math is searchable. This enables users to navigate documents and find the equations or parts of equations needed. This will also enable researchers to find equations online.
- Artificial Intelligence will have access to the math which will enable unlimited ways for users to learn and use these equations.
What is MathML?
MathML (Mathematical Markup Language) is an industry standard adopted by the W3C as the approved way of expressing math on the web. MathML is a markup language written in XML syntax. It describes structure and content of mathematical notation.
Using MathML provides the highest level of accessibility to math within digital documents. MathML equations will, for instance, increase in size as users change font size to increase readability. MathML also allows the synthetic speech user to set different verbosity levels, automatically adjusts for the user's native language, and supports aural navigation through complex math equations for better understanding. For Braille users, MathML supports various Braille math formats, subject to Braille translation software support. https://www.washington.edu/doit/what-mathml
The RCPD has been using MathML in XML or XHTML documents for several years to make accessible math for our students with disabilities. MathML is a universal format for math that is easily convertible into visible, audible, tactile and machine-readable forms.
Guides to Using MathType
Using MathType in Microsoft Word for Windows 10 computers
MathType is currently a free add-in that can be utilized in Microsoft Word, Excel, and PowerPoint. While MS Word provides some math creation tools built in, MathType is the preferred method as it offers greater accessibility.
To install MathType go to the Insert tab in Word and select Get Add-ins in the Add-ins group.
Type MathType into the search box and select the Add button
Once installed this MathType option will appear in your Insert menu. You can select it and enter math equations in a floating dialog box with many symbols and typed text or by handwriting equations.
Using MathType for Microsoft Word for Mac
To install MathType go to Insert tab, Add-ins, Store...,
then search for MathType add-in in the search box.
To insert an equation using MathType go to insert tab and select Math icon to open MathType Window. You can then type the equation or handwrite it.
Using MathType in Pages for Mac
Select MathType as preferred equation editor by going to Pages menu, preferences, then in Equation preferences selecting to use MathType.
To insert an equation, go to insert. Equations, then type equation in dialog box that appears. When finished close box, and equation will appear in Pages’ document.
Using MathType in D2L
Use MathType when inserting math equations in D2L. When creating content hit the 'Show All Components' button. Then in the drop-down equation menu, select Graphical equation. A MathType window will then appear to type or handwrite the equation.
Also see the Mathematical Expressions & MathML in D2L Tutorial.
Additional Help
More information about how to use MathType is found at the following link, https://docs.wiris.com/en/mathtype/start.
Creating Equations with LaTeX Input
LaTeX is a math markup language familiar to many in the science and math community, but unfortunately is not currently supported by screen reader technology. You can use the LaTeX input in MS Word to embed MathM as follows.
Use the hot key (Alt + =) or select the equation editor from the Insert ribbon menu...,
then select LaTeX input
You can now enter LaTeX such as 'frac{d}{dx}left(int_{0}^{x} f(u),duright)=f(x)' and it will convert to an accessible equation:
Using this newly available process for creating math in your handouts will enable many students with disabilities to access homework independently. It also saves many hours for RCPD staff who currently rewrite every equation for them.
MathML Rendering in Web Browsers
Getting MathML to render in web browsers is very complicated. However, many popular browsers have MathML support built-in. For example, Firefox and Safari have MathML support built-in.

Internet Explorer doesn't have support for MathML built-in, but can use the Math Player plugin from Design Science to enable support. Unfortunately, MathML is not supported in Microsoft Edge and Chrome. Using MathJax is an option that should make embedded MathML display correctly in browsers that support CSS2.1. D2L automatically uses MathJax.

Conclusion
While using MathType to create MathML is a 'giant leap' in accessibility, it does not satisfy all of the goals to create accessible math. A better way to deliver accessible math is through web pages as stated by W3C. https://www.w3.org/Math/.
The MSU 'Enhancing the Accessibility of Mathematics and Symbolic Content' project is currently developing a tool to easily embed MathML in online XHTML documents and web pages. This is the ultimate and universal design way to experience math with many potential learning enhancements. http://www.msumathonline.com/.
