What to do with my videos?

Hi!
I made math videos that cover complete courses from arithmetic through calculus 3 plus geometry, statistics, probability theory, differential equations and linear algebra. I also have many test prep videos like SAT, ACT, GRE, GMAT,...
I have been selling these on ebay and on my websites. I am thinking of putting all these videos on youtube (over 500 videos) and wanted to use adsense to monetize from these videos. I am wondering what you think of this idea? Also I am extremely new with this and am wondering if you do think this is a good idea then what do I need to do to get this idea going other than uploading these videos? That is how do I get these videos viewed by people??
Thanks!

why not trying .... i dont know if this is popular in YT.

why are you not selling them longer as you did before.

Here's an idea: Upload them to youtube. Once you've got around 10 videos uploaded, apply for their partnership (adsense) program. Keep uploading your videos. Start looking up questions on Yahoo answers and other sites like that and referencing your website as a source. At the same time, post your channel link in forums with math related questions. You can even post your channel link in programming forums too. Doing some SEO to your videos would help you with traffic as well. This should get you started, for anything further, look around the forum for Youtube SEO methods to help you out. Good luck!

If the videos are high quality enough then release part of them on YouTube for free with a link saying "Want more click here" and
have it redirect them to your website with affiliate links from companies like Texas instruments (not saying they have an affiliate
program) And you can also use a membership plug in with WordPress and charge people a small membership fee to view them

Sell them here:

http://udemy.com/

Then give out a free coupon to BHW members so that you can get "customers" and reviews of the product to make it look like you have a lot of customers. Much like Fiverr people at Udemy purchase based on the customer/review count.

I would upload them onto youtube, link them to a seperate wordpress site and then collect money off of youtube adsense and google adwords.

nah... udemy is the new in-thing...
you need to plug your courses and
traffic back to your website at least.
