I need the numbers of equations and brackets around to be in bold. Doing like this


only the number is produced in bold, how to bold brackets?

And second question. I want my references to equations also to be with bolded brackets automatically, how to do this?

  • Are you using the amsmath package? Commented May 23, 2012 at 17:16

You can redefine \tagform@#1 from amsmath.sty:




a = b.
As we see from equation~\eqref{eq:test}... 


enter image description here

  • Thanks! I didn't even used \eqref{} for this, thought that it should be done like this [\ref{}].

  • @Pavasaris you're welcome! The advantage of using \eqref over \ref is that the former automatically supplies the declared format around the equation number. Commented May 23, 2012 at 17:34

The »mathtools« package can do this job for you.

% !TeX program = pdflatex
\usepackage{mathtools}   % loads »amsmath«
