Change an equation that was written in a previous version of Word

Important:  This feature isn’t available in Office on a Windows RT PC. Want to see what version of Office you're using?

When you open a document containing an equation that was written in a version of Word prior to Word 2007, you need to use Equation 3.0 or the add-in that was used to write the equation to change it. Equation 3.0 is still available in Word 2013 and when you click in an equation written with Equation 3.0, it will open automatically.

  1. Double-click the equation that you want to edit.

  2. Make the changes that you want.

If you convert an older document to the current format, you can use Word 2013’s more powerful built-in tools to write an equation. However, any old equations written using Equation 3.0 or using an add-in must be manually recreated if you wish to use Word 2013’s built-in equation editor.

To convert a document, click File > Info > Convert.
