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 the base node to change its location and display type.
Assert.assertEquals(MathObjectType.O_MATH_PARA, officeMath.getMathObjectType());
Assert.assertEquals(NodeType.OFFICE_MATH, officeMath.getNodeType());
Assert.assertEquals(officeMath.getParentNode(), officeMath.getParentParagraph());

// OOXML and WML formats use the "EquationXmlEncoding" property.
Assert.assertNull(officeMath.getEquationXmlEncoding());

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

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