How can i draw a combination diagram?

Question

I need help making this types of diagrams

I tried to use \frac but it doesn't work because I need the equal symbol to be on top, also I tried to use \underline but I don't know if there is some way to put text below.

I've been thinking I could do it with \tikz, but I wanted to see if there's an easier way.

What do you mean by "combination diagram"? I see an equation and not a diagram (but I am not a mathematician). — Dr. Manuel Kuehner, Mar 17 '23 at 23:39

You could use an invisible fraction based on \genfrac from amsmath.

\documentclass{article}
\usepackage[fleqn]{amsmath}
\newcommand{\ifrac}[2]{\genfrac{}{}{0pt}{}{#1}{#2}}
\begin{document}
\[\frac{52}{1^\circ}\ifrac{\cdot}{}\frac{51}{2^\circ}\ifrac{\cdots}{}\frac{1}{52^\circ}\ifrac{=52!}{}\]    
or
\[\frac{52}{1^\circ}\ifrac{\cdot}{}\frac{51}{2^\circ}\ifrac{\cdots}{\cdots}\frac{1}{52^\circ}\ifrac{=52!}{}\]    
\end{document}

Thank you very much!, It's easier than I had thought. – Mons Mar 17 '23 at 23:55 — Mons, Mar 17 '23 at 23:55

Following David's answer here:

\documentclass{article}
\newcommand{\myVerticalRaise}{1.5ex} % Variable for vertical raise used in \raisebox.
\begin{document}
\begin{equation}
   \frac{52}{1} \mathrel{\raisebox{\myVerticalRaise}{$\cdot$}}%
   \frac{51}{2} \mathrel{\raisebox{\myVerticalRaise}{$\cdot$}}%
   \frac{1}{52} %
   \mathrel{\raisebox{\myVerticalRaise}{$=52!$}}
\end{equation}
\end{document}
