I'm editing a scientific paper that's been converted from a PDF to a Word .docx file. I need to re-create many complex equations, so I'm using Word 2007's built-in equation editor. The equations need to be centered, but some of them appear flush left. I'm not able to center them using the normal paragraph format tools, but a Google search says I just have to alter the MTDisplayEquation style. But I can't find that style anywhere: in the regular style dropdown, in the Styles list, or in Manage Styles. I could import the style, but I can't find a document containing equations created with Word's equation editor.

Any ideas where I can either find the style in my document or import/download it from somewhere?

AFAIK, Word doesn't come with an MTDisplayEquation style, so it's probably a custom one someone created.To see how to do that, visit:

Thank you, Paul. You're right; I've just discovered that the style is added by a math equation editor called MathType, which is similar to Word's built-in Equation Editor but adds many features. The nonacademic version is $90, so I think I'll content myself with leaving the equations flush left.
