## Remarks


In this version of Aspose.Words, [OfficeMath](./) nodes do not provide public methods and properties to create or modify a [OfficeMath](./) object. In this version you are not able to instantiate [Math](../) nodes or modify existing except deleting them.

[OfficeMath](./) can only be a child of [Paragraph](../../aspose.words/paragraph/).

## Examples



Shows how to set office math display formatting. 
```cpp
auto doc = System::MakeObject<Aspose::Words::Document>(System::String(get_MyDir() + u"Office math.docx"));

auto officeMath = System::ExplicitCast<Aspose::Words::Math::OfficeMath>(doc->GetChild(NodeType::OfficeMath, 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_EQ(MathObjectType::OMathPara, officeMath->get_MathObjectType());
ASSERT_EQ(NodeType::OfficeMath, officeMath->get_NodeType());
ASPOSE_ASSERT_EQ(officeMath->get_ParentNode(), officeMath->get_ParentParagraph());

// Change the location and display type of the OfficeMath node.
officeMath->set_DisplayType(OfficeMathDisplayType::Display);
officeMath->set_Justification(OfficeMathJustification::Left);

doc->Save(get_ArtifactsDir() + u"Shape.OfficeMath.docx");
```
