I have LibreOffice 4.0 and Kubuntu 12.04. I have worked on a .docx file from Microsoft Office 2010 and I have used math symbols.

How can I solve it? If I enlarge the symbols from the picture above, I can see the function I wrote but in my file there many many symbols like those so I can't edit each of them.
