# Second level headers: start counting from 0

I'm using Pandoc. I found this answer but it works on first-level headers only.

How can I offset second-level headers so that they are:

1

1.0

1.1

1

1.1

1.2

?

\setcounter{subsection}{-1}


doesn't seem to be working.

• It would be easier to help you if you will provide (non)Working Minimal Example ... – Zarko Nov 1 '16 at 0:12

• A minimal example is something we can compile. Many potential helpers will not be able to compile that. You will stand a better chance of getting answers if you paste code for a minimal document in a format everyone can work with i.e. a .tex file e.g. TeX or LaTeX or ConTeXt or whatever. – cfr Nov 1 '16 at 2:45
• Each time you say \section, the subsection counter is reset to zero. If you just wanted continuous numbering from zero, that would be fairly straightforward. But for this you'll need to change the reset code rather than eliminating it. This depends on class etc., too. I've no idea what the code produced by pandoc looks like in general or in your environment in particular. – cfr Nov 1 '16 at 2:47

\setcounter{subsection}{-1}

\renewcommand{\thesubsection}{\thesection.\number\numexpr\value{subsection}-1}

This changes only the representation of the \subsection counter to be one less than it actually is. This would also work with references, if needed.
