Arithmetic categories have been updated. I will get Pre-algebra categories done, then it will be time to go back and in the few pages that KA has released over the past few weeks. I will also delete the challenge patches and pages that were associated with Arithmetic and Pre-algebra a long time ago but are no longer needed.

Also, if anyone is interested in making exercises, I created a template so you can copy and paste the same "consistent" format. It is located at Template:Exercise. You can look at any exercise page to get the general feel of the information we want there.
