2 @DávidTóth – You should insert \label directives at the end of each line (but before \`) in a gather` environment.The equation number, since it does not get flushed to the right (as it does by default in display math), may be mistakenly interpreted as part of the inline equation itself.

See also aligned as pointed out in an answer below. But if you really want it to be like this you could use the \setcounter-command twice before and after the equation to make the equation number 1. Well, worth asking anyway! 🙂 equations.Numbered environments in LaTeX can be defined by means of the command \newtheorem which takes two arguments: \newtheorem{ theorem }{ Theorem } the first one is the name of the environment that is defined.

I guess this more of a LaTeX thing than an RMarkdown thing. Here’s what I have right now: There are those who consider that papers look untidy with numbers on every equation; there is also a school of thought that claims that there should be numbers everywhere, in case some reader wants to make reference an equation to which the author made no cross-reference.

Sorry if the question is worded a bit weirdly, but basically, I like how the text looks when it’s centered nicely using align, but I don’t like the equation numbering on the right hand side of it. Both issues are simply artifacts of the maths mode, in that it treats it as a mathematical expression: spaces are ignored (LaTeX spaces mathematics according to its own rules), and each character .Numbers for referenced equations only. reqno Place equation numbers on the right. answered May 11, 2019 at 13:58.equation-number), use the \numberwithin command in the preamble of your document: \numberwithin{equation}{section} For more details on custom numbering schemes see [Lam, x6.
