I am creating a presentation where I have equation numbers.

I decided to show all the numbers to make it easier for the audience to refer to individual equations.

I would like to ask if there is a simple method to make the displayed numbers smaller than normal.

    See the documentation of the mathtools package (p.9-10): it has a \newtagform command to customise the appearance of equation numbers

To expand the comment of @Bernard,

\newtagform{smalleqnum}[\tiny]{\tiny (}{)}

Solved my problem nicely. Let me also add the link here.

    The \usetagform instruction can be simplified to \newtagform{smalleqnum}{\tiny (}{)}, as the \tiny directive is a switch, i.e., its scope doesn't end until the current TeX group ends.
