I am running Lyx 2.0.2. I have amulti-line formula that I created via the "Insert Matrix" command. Iwould like to number each line in the formula. However, when I trythis: Edit | Math | there are two choices: Number Whole Formula orNumber This Line. However, they seem to be the same thing.The problem is that a matrix does not really give you a multi-lineformula, it is a one-line formula including a matrix. To get amultiline formula, use one of the aligned environments. I prefer theeqnarray environment. Then you can number each line of the multi-lineenvironment. I will attach a simply LyX file showing first aneqnarray environment, then a matrix environment, both numbered, butthe matrix only allows numbering of the whole thing.

`The gather environment will also do, or the equation array environment,`

`but not, perhaps surprisingly, the multiline environment, which is`

`specifically intended to a single equation that spans many lines`
