**Public API Changes**

**Exporting mathematical equations to MathML format**

Methods **IMathParagraph::WriteAsMathMl()** and **IMathBlock::WriteAsMathMl()** have been added. You can use them to export a mathematical paragraph or block to MathML format. The presentation MathML markup is used.

```
using namespace System;
using namespace Aspose::Slides;
auto pres = MakeObject<Presentation>();
auto autoShape = pres->get_Slides()->idx_get(0)->get_Shapes()->AddMathShape(0.0f, 0.0f, 500.0f, 50.0f);
auto portion = autoShape->get_TextFrame()->get_Paragraphs()->idx_get(0)->get_Portions()->idx_get(0);
auto mathParagraph = (DynamicCast<MathPortion>(portion))->get_MathParagraph();
mathParagraph->Add(MakeObject<MathematicalText>(u"a")->SetSuperscript(u"2")->
Join(u"+")->
Join(MakeObject<MathematicalText>(u"b")->SetSuperscript(u"2"))->
Join(u"=")->
Join(MakeObject<MathematicalText>(u"c")->SetSuperscript(u"2")));
auto stream = MakeObject<IO::FileStream>(u"mathml.xml", IO::FileMode::Create);
mathParagraph->WriteAsMathMl(stream);
stream->Close();
```

Contents of the resulting file:

```
