I am trying to number my theorems according to section number. I use the following in the preamble, which works:

\newtheorem{theorem}{Theorem}[section]

However, since my section is numbered as roman numeral, my theorem numbering ends up being like

Theorem IV.1

Which is really ugly. I would like to keep my section numbering as Roman numerals but my theorem numbering as Arabic. I've tried stuff like

\newtheorem{theorem}{Theorem}[\arabic{section}]

But this wouldn't compile. I've also looked around online but couldn't find the answer.

Pleas let me know if you know a solution to this problem. Thank you!!

Try

\renewcommand\thetheorem{\arabic{section}.\arabic{theorem}}
