I just recreated this page:

http://khanacademy.wikia.com/wiki/Matrix_dimensions

Should I add categories like Precalculus:XOX and Algebra II: XOC, Algebra II exercises, etc to it?

I see that you have not yet created cats. for those missions.

I have left it with just the "Math exercises" category for now.
