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.

Right!!
using library takes all the fun and difficulty out of challenges

cool, you thought of all kinds of returns, but then you overload your function when it could only do one thing, the only thing it needs to do is turn positive into negative, positive is all those above 0, so
num > 0 return "some way to pass it negative", the rest can be returned the number itself, so just put areturn num
