✅ best LINQ method to sort after subtracting two properties?

I have a list of objects with two fields, num1 and num2. I would like to subtract num1 by num2 and then sort descending by the resulting value. Can anyone recommend a LINQ method for this?

OrderByDescending?

list.OrderByDescending(foo => foo.Num1 - foo.Num2);

list.OrderByDescending(foo => foo.Num1 - foo.Num2);

wait do you want a return list of just the result of this substraction tho?

ah yeah, maybe i misread the question that'd be

list.Select(foo => foo.Num1 - foo.Num2).Order();

list.Select(foo => foo.Num1 - foo.Num2).Order();
