# Getting \boldmath to always change to a bold font when mathptmx is used

I found the question "Is there any way other than \pmb to produce bold greek letters when mathptmx is used?". Could somebody show how to make \boldmath always change to a bold font when mathptmx is used? I assume that the answer to the former question applies only to getting bold Greek letters. I know that the result will probably look ugly; I'm just curious if there's a simple way to do this without changing to a different package.

• mathptmx (which is very old and not the recommended way of getting times like math these days) has no bold, so you have to load additional fonts for bold, so it would be odd not to load matching fonts for normal weight, this works for example: \documentclass{article} \usepackage{newtxmath} \begin{document} $\alpha+x$ \boldmath $\alpha+x$ \end{document} – David Carlisle Sep 15 '18 at 8:18
