I have a math expression that looks like this






Now I tried by setting \hspace{5mm} between lines that have =0 in them (first line, fourth line, etc.), so that I have some kind of self contained portions in the expression, so that the reader could see that this is just a manipulation of the first expression. But \hspace did nothing. Is there a way to do this? I would like to separate certain parts, so that they stand out a bit, but not actually separating the whole expression (I hope I'm clear enough).


Here's a sketch what I want

I might mean vertical spacing, I always confuse those two xD

  • Where should the extra space go, exactly? Did you mean vertical spacing? Could you post a sketch of the desired output? – jub0bs Nov 11 '13 at 20:38

    You want something like \\[2ex] at the places after which you want bigger vertical space. – egreg Nov 11 '13 at 20:50

    @Karlo You don't have to fix every single little typo you find on the site. It's good that you do "maintenance", but also consider that when you do a lot of edits at once you're flooding the front page, so new questions that need more attention disappear quickly. And I would say think twice if you're only fixing one or two typos. If more substantial edits are needed, including tags and formatting, that's another story. Main point: try to do such things in smaller batches. – Torbjørn T. Apr 29 '16 at 12:17

  • @TorbjørnT. OK, didn't know that. – Karlo Apr 29 '16 at 12:41

You can use \\[<dimen>] at the end of a line in align, split and similar alignment environments. I guess that


is good for this, where you want more vertical space.
