Does anyone know of a tool I can use?

I'm looking for a sort of re-arranging calculator. Like I have 3 sets (For ex: A, B, C) in a Venn Diagram.

Say I have A U B. I want to put "A U B" in the calculator and get 'other sets that are equal to but using a different combination of the basic operators'.
For instance, ((A U B)')' would be a valid answer (and more).

Anyone know if this exists?

  1. Wait patiently for a helper to come along.
  2. Once someone helps you, say thank you and close the thread with:
+close
  1. Feel free to nominate the person for helper of the week in #helper-nominations
  2. Do not ping the mods, unless someone is breaking the rules.
  3. If you're happy with the help you got here, and the server overall, you can contribute financially as well:

Unfortunately it doesn't show formulas between cardinality, like the famous:
|A union B| = |A| + |B| - |A intersect B|
