How to center equations?

Hi all,

How do I set all the math equations to be centered rather than left aligned? I want to avoid doing it one by one.

I tried styles-and-formating → Formula → Modify → Type, but then the Horizontal Position option is blocked I cannot edit it.

You have to anchor them to a paragraph, not as character. So insert equation in a new paragraph. Do right click, choose Object and in tab Type do ‘to a paragraph’ and then at the bottom of that dialog box for Horizontal set ‘Center’.

Thanks. I have tried this approach and it works for all the equations in the document if I copy/paste the formated one.
