[Tex/LaTex] Remove numbering from Section and Subsection

numberingsectioning

I found this answer to remove the numbering from sections, but I also don't need numbering on sub– and subsubsections.

I tried to add a second def but then the number on Section is showed again.
I am fairly new to Latex and I don't really know what is going on in this code block.

Original:

\makeatletter
\def\@seccntformat#1{%
  \expandafter\ifx\csname c@#1\endcsname\c@section\else
  \csname the#1\endcsname\quad
  \fi}
\makeatother

Mine:

\makeatletter
\def\@seccntformat#1{%
  \expandafter\ifx\csname c@#1\endcsname\c@section\else
  \csname the#1\endcsname\quad
  \fi}

\def\@seccntformat#1{%
  \expandafter\ifx\csname c@#1\endcsname\c@subsection\else
  \csname the#1\endcsname\quad
  \fi}
\makeatother

Since you don't want numbering, use \setcounter{secnumdepth}{0}

\documentclass{article}
\setcounter{secnumdepth}{0}
\begin{document}
  \section{A section}
  \subsection{A sub section}
  \subsubsection{A sub sub section}
\end{document}

[Tex/LaTex] “Automatic” section labeling

I'm not entirely sure I have understood the question, but here goes.

You can \renewcommand the \section, \subsection, etc commands to add the \label of your choosing. The tricky part is that each of these commands take an optional argument (for the headers and toc). Luckily, this has already been tackled in a previous question

"Closed" (square) root symbol

Here's a MWE- if I've misunderstood, please let me know

\documentclass{memoir}

\usepackage{letltxmacro}
\LetLtxMacro{\oldsection}{\section}
\renewcommand{\section}[2][]{\oldsection[#1]{#2}\index{#1}\label{sec:#1}}


\begin{document}

\section[drowning]{Drowning}
Test reference \ref{sec:drowning}
\end{document}

[Tex/LaTex] Section and subsection numbering

You need to pass the appropriate counter to the third required argument of \titleformat. Currently you just have written {} instead of e.g. {\thesection}. Here is a complete example, with left alignment rather than centering:

Sample output

\documentclass[12pt,a4paper,oneside]{article}

\usepackage{titlesec}

\titleformat{\section}[block]{\Large\bfseries\filright}{\thesection}{1em}{}
\titleformat{\subsection}[hang]{\bfseries\filright}{\thesubsection}{1em}{}

\begin{document}
\section{Sun}
\subsection{Moon}
\section{Bed}
\end{document}
