I am looking for an environment that makes the following align properly:

\documentclass{report}

\usepackage[a4paper]{geometry}
\usepackage{multicol}
\usepackage{amsmath}
\usepackage{amsthm}


\begin{document}
\begin{multicols}{3}
  \begin{equation}
    \frac{\begin{gathered} here \ are \ three ~ lines \end{gathered}}{conclusion}
  \end{equation}
  \begin{equation}
    \frac{\begin{gathered} here ~ are \ two ~ lines \end{gathered}}{conclusion}
  \end{equation}
  \begin{equation}
    \frac{\begin{gathered} here ~ is ~ one ~ line \end{gathered}}{conclusion}
  \end{equation}
  \qed
\end{multicols}
\end{document}

enter image description here

That is:

  • I have several equations that I want to display side-by-side
  • I cannot use align or things like that, as I want to maintain each equation as one unit. I thus cannot combine every line with &. Furthermore, they do not always consist of line of equal sizes.
  • The \qed should appear at the height of the longest equation, which can be any position (1 in this case)
  • Ideally, I can adjust the alignment of the equations shorter than the longest equation (i.e. switch between top, center, or bottom aligned.

  • For the text you can use or \mathrm or \text: it is better. – Sebastiano Jul 10 '20 at 15:53

    Thans @Sebastiano, the text in the example is just that: an example (my real document contains much more complicated equations). However, is there any difference between \mathrm and \text? – R. Bosman Jul 10 '20 at 15:56
  • For my humble opinion there are very similar. But here there is an answer: https://tex.stackexchange.com/questions/88794/difference-between-mathrm-operatorname-and-text?noredirect=1&lq=1 – Sebastiano Jul 10 '20 at 16:00
