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.

Nice and simple. I solved with somewhat same thing, but your's is concise and beautiful.

Calc.new.four.plus.four.times.tworeturns16whileCalc.new.four.times.four.plus.tworeturns18which is correct.For ruby, it is too much for 6kyu, In my humble opinion
