The issue is we only teach one method for approaching Maths so if you don't get it, tough.
In primary and secondary school I always struggled with Maths. During university I spent most of my energy reverse engineering the maths lessons so I could understand them.
Years later my sister was struggling with her Maths GCSE, I spent one evening explaining how I solve each type of problem. She went from a projected D to getting an A.
I was explaining this to an ex maths teacher who started asking how I approached things. Apparently I used the Indian method for one type of problem, the asian for anouther, etc..
The idea a student was struggling with one way of solving the problem and teaching them alternative methods never occurred because it was "outside the curriculum".
These days I quite like Maths puzzles.
If its for work I would suggest picking a "stable" distribution like Debian, Kubuntu or OpenSuse.
A lot of people recommend Arch or Fedora but the focus of those is getting the very latest releases, which increases your chance of stuff breaking.
A lot of people will suggest niche distributions, those can be great for specific needs but generally you will always find Debian/Ubuntu/RHEL support for commercial apps.
I would also suggest looking at the KDE Desktop, many distributions default to Gnome but it is unique in how it works, KDE (or XFCE) will provide a desktop similar to Windows 11.
Lastly I would suggest looking at Crossover Linux by Codeweavers.
Linux has something called WINE, its an attempt to implement the Windows 95 - 11 API's so windows applications can run on linux.
WINE is how the Steam Deck/Linux is able to play Windows games. Valve embedded it into Steam and called it "Proton".
WINE is primarily developed by Codeweavers and they provide the Crossover application that makes setting up and running a Windows application really easy.
People will mention Lutris but that has a far higher learning curve.
There is an application database so you can see in advance if your applications would work: https://appdb.winehq.org/
