I have noticed that the environment align appears to do everything that the environment equation accomplishes, plus the additional features of aligning equations and arranging them in an organized manner on the page.
I have started writing up some lecture notes and have noticed that I use align so often that I now use it in place of equation!
Are there any reasons why I should not do this? ie; why I would want to use the equation environment when I don't need all the features of align? or is it acceptable to use align throughout my document?
equationhas some space saving features thataligndoes not. Thus if you know what to look for you'll often be able to see when an author has been usingalignfor one-liners. – daleif Oct 10 '16 at 14:11texdoc amsmathgather is for multiple equations with no alignment, also multline which is for a single but multi-line equation with no alignment – David Carlisle Oct 10 '16 at 15:45
