I have no idea of a prize, except my undying gratitude! Maybe a dollar. I will make a KA wiki dollar with your name on it and give it to you!

I went through each exercise page and all categories are up-to-date. According to Category:Math exercises we have 951 exercise pages but Khan Academy says there are 952 :(

That means in all likelihood, someone (probably me) made an exercise page and forgot to put the category "Math exercises" on it.

These is a possibility that the exercise is actually one that is on KA that we do not have here. I found two of those today (see Geometric definitions and Points, lines, and planes) but this is a very unlikely scenario. If you look at these pages you will find that although they are part of the Geometry Math Mission they do not appear on everyone's Geometry dashboard! By the way, they might just not be appearing on mine, I will put a screenshot up on my profile so y'all know I am not crazy.

So, the competition is:


 * 1) go through all of our exercise pages and find the one that is missing the "Math exercises" category, OR
 * 2) go through all exercises on KA and find the one that is missing from our exercise lists.
