Hey, Fish, I used to be a high school math teacher (go ahead, make your girl geek jokes
).
I now work for a textbook publisher making math books/digital content. I'm swamped at work right now, but I'll get back to you with some websites. I know there are a bunch of youtube videos about math -- don't know how good any of them are.
EDIT: If you have specific math questions, feel free to PM me.
