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.

?*11=?? it can be 3, 4, 5, 6,7,8,9
8997+987?9=1077?6 in this random generated example both 0 and 2 work. OR another mistake in random example that I encountered is ?*11=??

You just return none. You should write a return function. Not just print the result in a function.
