So, I'm writing a mathematics paper, and let's say I have the following:


Is this the proper way to do an unnumbered equation, or is it preferred to do the following:

\[ 2+2=4 \]

My question really is: what's the difference between doing \begin{equation*} and \begin{equation*} versus doing \[ \]? Is there a setting in which one may be preferred over the other?

Thanks in advance.

  • The equation environment gives you a numbered displayed formula, not equation* nor \[..\]. Note that you need the amsmath package for the equation* environment. With this package loaded, equation* has then the same meaning as \[..\] (unnumbered displayed formula).

  • Also have a look at this: tex.stackexchange.com/questions/503/why-is-preferable-to and read the comments there. – AboAmmar Apr 9 '15 at 5:05
  • Thank you fpast and AboAmmar! Your comments and the articles to which you linked were quite helpful. – 3.14 - Thon Apr 9 '15 at 5:26

equation* is defined by amsmath. So, if you're loading amsmath, then there is no difference amsmath, as it executes the following at the end:
