# Using the Equation Editor

### What?

The Equation Editor allows myWPI users to add mathematical and scientific notation to items, assessment questions, announcements, and discussion board postings. Users can add equations and edit existing equations. The Equation Editor symbols are based on MathML, a markup language for math on the Web. MathML is a subset of XML.

## Accessing the Equation Editor

- Go to the item, announcement, assessment question, or discussion board posting where you want to add an equation.
- In the box for adding text or a description, click on the toolbar button for the Equation Editor: . The Equation Editor opens in a new window.

### Note

If you are using a Mac with Safari as your browser, you must turn off the visual text box editor by going to *Course Tools* > *Personal Information* > *Set Visual Text Box Editor Options* and selecting the *Unavailable* option. The Equation Editor button will then be available for accessing the Equation Editor.

## Entering an Equation

- In the
*Equation Name*field, enter a name for the equation, if desired. - Change the
*Font Size*, if desired. - Use the Equation Editor toolbar to select the appropriate notation or use your keyboard.
- Click
*Submit*when finished. The equation appears in the text area of the item, announcement, question, or discussion board posting. You can continue by adding additional text.

### Tip

If you only need to create equations with subscript and superscript characters, you can do so within the visual text box editor. If the visual text box editor is unavailable to you because you either use a browser that does not support it or you have manually turned it off, you can use HTML code to indicate the subscript and superscript formatting.

## Editing an Equation

- If the location of the equation is an announcement, item, or question, click
*Modify*. - Click on the equation and then click the Equation Editor button:
- Make the necessary changes and click
*Submit*.

## Using the MathML Editor

If you are familiar with XML, you can create an equation using MathML code.

- Go to the item, announcement, assessment question, or discussion board posting where you want to add an equation.
- In the box for adding text or a description, click on the toolbar button for MathML: . The Math ML Equation Editor opens in a new window.
- Enter the code for the equation and click
*Submit*when finished.
