You can insert math equation image using DocumentBuilder.InsertImage method. It will insert as image into document. However, you can insert MathML using DocumentBuilder.InsertHtml method as shown below. Hope this helps you.

```
Document doc = new Document();
DocumentBuilder builder = new DocumentBuilder(doc);
builder.InsertHtml(
"<math xmlns = \"http://www.w3.org/1998/Math/MathML\">" +
"<mfrac>" +
"<msup>" +
"<mn>5</mn>" +
"<mfrac bevelled=\"true\">" +
"<mn>6</mn>" +
"<mn>7</mn>" +
"</mfrac>" +
"</msup>" +
"<mn>8</mn>" +
"</mfrac>" +
"</math>");
doc.Save(MyDir + "20.5.docx");
```
