To the first question, by the end the number of exercises will be equal, but to do that I have to go into every page that was given a "Category: Math exercises" tag where it was not appropriate. That is why the number is at 620 even though we have not made 620 exercises pages (Example: http://khanacademy.wikia.com/wiki/3rd_grade_(U.S.):_Addition_and_subtraction this page has a Math exercise tage, although it is not a math exercise).

To the second question, I just created it, so it will probably take a day for the wikia servers to officially recognize it. The same thing happens to me when I make a new category. It doesn't show up immediately, but usually by the next day. (Example: http://khanacademy.wikia.com/wiki/Reading_and_setting_clocks has this new "Category:Previous math exercises" tag so it might be one of those exercises that disappeared when the counts go down slowly and mysteriously).

PS: KA just did a MAJOR OVERHAUL of the order of the exercises in WofM. They didn't add or remove anything (yet), but the order is wildly changed (I know, because I just researching the order and I came back 20 minutes later and things were way different). This could be a sign of a new influx of exercises. If I were you, I would be expecting to update WofM number of exercises very soon!
