Union, intersection, difference, symmetric difference and unique elements over two editable number lists, sorted ascending with a count for every result.
Duplicates are kept in the input so you can see them collapse: type the same value twice and the count beside each operation tells you the set-theoretic size, not the number of entries you typed. Values are sorted ascending, and 2 and 2.0 count as one element.
