I came to the same conclusion about having to recreate numerals using lambda calulus and didn't think the prof really wanted his students to do this on an exam. I also thought he wanted input/output in numerals (1, 2, 3...) instead of lists like ('(()), '(() ()), '(() () ())) so I gave up.

Nice work.
