Page Layout ⇒ Document for comparing calculations

[Equilibrium]

Hello Latex Community,

I often have to compare results of different approaches or calculations. For this I would like to create a suitable document with Latex.
The document should be divided in half of the page (A4). On the respective side should then be the calculations to be compared. At the end of a comparison I would like to be able to summarize the difference. The summary of the result should then run over the entire page again.
Subsequently, the page should be divided again to compare another part of the calculation with each other.

In the picture I tried to sketch this - I hope my approach of the document is understandable.


I do not expect a finished latex code. I would be already grateful if someone has a tip, how I could approach it. My Latex skills are not so good that I know directly meaningful approaches here.


For every tip thankful!

Package parallel or the somewhat more generic multicol come to mind.
