## OfficeMath class

Represents an Office Math object such as function, equation, matrix or alike. Can contain child elements
including runs of mathematical text, bookmarks, comments, other [OfficeMath](./) instances and some other nodes.
To learn more, visit the [Working with OfficeMath](https://docs.aspose.com/words/python-net/working-with-officemath/) documentation article.




### 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
[aspose.words.math](../) nodes or modify existing except deleting them.

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




**Inheritance:** [OfficeMath](./) → [CompositeNode](../../aspose.words/compositenode/) → [Node](../../aspose.words/node/)

### Examples

Shows how to set office math display formatting.

```python
doc = aw.Document(file_name=MY_DIR + 'Office math.docx')
office_math = doc.get_child(aw.NodeType.OFFICE_MATH, 0, True).as_office_math()
# 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.
self.assertEqual(aw.math.MathObjectType.O_MATH_PARA, office_math.math_object_type)
self.assertEqual(aw.NodeType.OFFICE_MATH, office_math.node_type)
self.assertEqual(office_math.parent_node, office_math.parent_paragraph)
# Change the location and display type of the OfficeMath node.
office_math.display_type = aw.math.OfficeMathDisplayType.DISPLAY
office_math.justification = aw.math.OfficeMathJustification.LEFT
doc.save(file_name=ARTIFACTS_DIR + 'Shape.OfficeMath.docx')
```
