How to centre equations?

I see that the last equation has a mind of its own. Is there any trailing white space after the equation in the editor, or already on that line that is forcing the alignment left of the expected centered position? I am wondering if your attempt to generate that index in the editor isn't causing it to insert trailing blanks.

Here is a visually correct solution that uses a denuded table with the equation centered in the middle cell, and the manually inserted (index), right justified in the right-most cell.

Looks good but an annoyance with many equations. The time that you spend fooling with this could have been written in LaTeX. 😉

You are using Pages v6.1, as opposed to any other Pages (with MathType) correct? If Pages v6.1, click on your equation object to select it. On the right panel under Format Text Style panel, click the center text alignment. That is all that I did to align the entire equation.

Post a screen grab of before and after in your next response.

Were you looking for the equation to be centered, and the equation counter right justified as can be done in LaTeX?

As far as I have discovered, the Pages equation editor doesn't display the equation count, so you must be manually creating these in the equation editor. Correct?

Good. Was that an ordinary space, or a non-breaking space (option+spacebar)?

By the way, a table cell is like a roach motel for equations. You can insert one, but no amount of double-clicking of the equation afterwards will open the Equation editor again. Always something.

Not being very experienced with my new iPad, my first guess was what you already tried! In a perfect world, that would have worked! My second choice is the old-fashioned-work-it-out-with-you-head-and-hands method. You know, find the middle of the paper and the middle of the equation, then type the appropriate number of spaces in, then the equation, then again the same number of spaces to finish your masterpiece. Check your calculations by printing before sending it out to avoid embarrassmeant since this method is sorta tough because the computer can be picky! If I remember right, (high school was a long time ago) there are 66 spaces to one line of type. Better check that last bit out on the net.

Click once on the equation, and then use the text center alignment. The entire equation is now centered on the current line in the page.

Other than adding a space character before the equation (or after it), a center-aligned tab stop can be used. Check the below page on how to create such a tab.

Numbers for Mac: Set tab stops in a Numbers spreadsheet

To avoid setting up a tab stop each and every time, a new style can be created upon one of the existing equations in a center-aligned tab stop. This new style, then, can be used for all lines with an equation while placing just a tab (instead of a space!) before every equation.

@DavKovacs: Can you pls mark your question as solved and point to the answer, i.e. your remark about inserting a space? Also seeing the two "I also have this question" marks, I thought it is yet to be still solved at first and accidentally noticed it actually was solved..
