Loading collection data...
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.

Concept is one thing, my complaint is for inconsistent description.
Task descriptions should be stand alone thing which covers everything you need to know to solve the task.
And you should refer to things the same way you defined them on top.
Example: "!" -> add data cell, but then you refer to it as "add to memory".
We shouldn't have to decifer descriptions to solve the kata, just sayin.
Ahh, i see.
So to completely make sense of the description, one needs to do all the related tasks in order?
Description is unclear, inconsistent and you keep calling decrement "increment -1".
