Collections are a way for you to organize kata so that you can create your own training routines. Every collection you create is public and automatically sharable with other warriors. After you have added a few kata to a collection you and others can train on the kata contained within the collection.

10 should equal 105
-10 should equal -105
201 should equal 2016
105, -105, and 2016 don't end with 0
