If any of you have been wondering what my last 30-35 edits have been about,

Well, I found many exercises(30+) like this http://khanacademy.wikia.com/wiki/Teen_numbers_2?oldid=74309.

As you can notice, there is an extra one line space between the end of types of problems and the strategies heading. I cleared that. I'll search for more pages like that tomorrow.

If any of you have any more doubts, feel free to post a new message on my wall.
