I can successfully copy equations made using the insert equation tool in MS word (2013) to the clipboard in MathML format for use elsewhere. However I mainly need to import into Word. Is there a way to import MathML format equation into word to be used as equations?
Did you just tried to paste any MathML fragment copied from, for example, notepad?
It worked for me. Just Copy and paste the following first into notepad and, then, copy from notepad and paste it to word:
<math xmlns="http://www.w3.org/1998/Math/MathML"><mfrac><mn>1</mn><mn>2</mn></mfrac></math>
