I need to change my section numbering from Arabic, to Roman, beet keep the Arabic numbering in subsections and subsubsections. For example:
I. Section
1.1. Subsection
1.1.1. Subsubsection
II. Section
2.1 Subsection
...
So I know that with sections i can do "\renewcommand \thesection{\roman{section}}", but this command changes also subsections and subsubsections, like that:
I. Section
I.1. Subsection
I.1.1. Subsubsection
II Section
II.1. Subsection
...
So I need to keep subsections ans subsubsections from Roman numbering.
These two lines did it for me:
\renewcommand \thesection{\roman{section}}
\renewcommand \thesubsection{\arabic{section}.\arabic{subsection}}
Subsubsection also works, I assume because it takes its section number from subsection.
