This page describes how to use the Equation style. This style is used for display equations that form one or more entire paragraph. It can be used irrespective of whether the equation contains only keyboard text or has been produced using Microsoft Equation 3.0, MathType or the Microsoft Equation Builder.

Equation

The Equation style is applied to equations that form one or more entire paragraph. It must not be applied as a character style to inline equations that form part of a larger paragraph. It can be applied to regular Word keyboard text, or to MathType, Equation 3.0 or Equation Builder objects. The XML output will depend on which export filter is used, and on whether the equation was typed from the keyboard or constructed with a math-editing package (in which case, an image and/or MathML of the equation may be produced).

Example

The following example demonstrates the use of the Equation paragraph style. Note that Word Field Shading is set to "Always" in this example. This illustration is an excerpt from the sample document:

JATS XML Example with MathML

<p>When you convert equations from Word to MathML, you may encounter differences between the MathML created by different equation editors. MathType objects will convert to a slightly different MathML than Equation Builder objects. For example, the equation
<disp-formula id="e___1">
	<mml:math id="m2">
	 <mml:mrow>
	  <mml:mstyle displaystyle="true">
	   <mml:munder>
	    <mml:mo>&#x2211;</mml:mo>
	    <mml:mrow>
	     <mml:mi>i</mml:mi><mml:mo>,</mml:mo><mml:mi>j</mml:mi></mml:mrow>
	   </mml:munder>
	   <mml:mrow></mml:mrow>
	  </mml:mstyle></mml:mrow>
	</mml:math>
</disp-formula>
created in MathType and Equation Builder yield the following MathML snippets:</p>
