# Labeling math equations [closed]

In .tex documents, when I am displaying an equation I do this:

$$a^2+b^2=c^2$$


And it displays with an equation number off to the right.

But when displaying proofs (where lots of work / equations / formulations may be present in a group), is there a standard convention for how these are to be displayed? Would an entire group be stashed between equation tags (and therefore assigned an equation number, cumulatively), or is there a way to display mathematical work without any particular assignment?

• Starred versions of many math-enviroments produces equateions with no tag , and you can then assign a custom tag with \tag{<text>} – Runar Dec 27 '15 at 19:09
• Instead of ..., use $...$ or \begin{equation*}...\end{equation*} if you've loaded amsmath. – Werner Dec 27 '15 at 19:09

• Welcome to TeX.SX! I'm afraid this is not a TeXnical question, but rather a stylistic problem. We can discuss how to implement a convention, not what convention you should follow. – egreg Dec 27 '15 at 19:32
• There are several conventions in mathematics; some people number each displayed formula, other just those they make reference to; in other fields numbering is rare and just some displayed formulas are tagged for reference. – egreg Dec 27 '15 at 20:26
