Example:

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

// When we save the document to HTML, we can pass a SaveOptions object
// to determine how the saving operation handles OfficeMath objects.
// Setting the "OfficeMathOutputMode" property to "HtmlOfficeMathOutputMode.Image"
// will render each OfficeMath object into an image.
// Setting the "OfficeMathOutputMode" property to "HtmlOfficeMathOutputMode.MathML"
// will convert each OfficeMath object into MathML.
// Setting the "OfficeMathOutputMode" property to "HtmlOfficeMathOutputMode.Text"
// will represent each OfficeMath formula using plain HTML text.
HtmlSaveOptions options = new HtmlSaveOptions();
{
    options.setOfficeMathOutputMode(htmlOfficeMathOutputMode);
}

doc.save(getArtifactsDir() + "HtmlSaveOptions.OfficeMathOutputMode.html", options);
