Example:

Document doc = new Document(getMyDir() + "Office math.docx");

OfficeMath officeMath = (OfficeMath) doc.getChild(NodeType.OFFICE_MATH, 0, true);

// OfficeMath nodes that are children of other OfficeMath nodes are always inline
// The node we are working with is a base node, so its location and display type can be changed
Assert.assertEquals(officeMath.getMathObjectType(), MathObjectType.O_MATH_PARA);
Assert.assertEquals(officeMath.getNodeType(), NodeType.OFFICE_MATH);
Assert.assertEquals(officeMath.getParentParagraph(), officeMath.getParentNode());

// Used by OOXML and WML formats
Assert.assertNull(officeMath.getEquationXmlEncoding());

// We can change the location and display type of the OfficeMath node
officeMath.setDisplayType(OfficeMathDisplayType.DISPLAY);
officeMath.setJustification(OfficeMathJustification.LEFT);

doc.save(getArtifactsDir() + "Shape.OfficeMath.docx");
