Well, it says on the rules that Algodoo is a place where users can have fun and learn. I didn't fell like typing in all caps was "fun" or "learning"
I'll quit.
Three reasons:
1. These challenges use lots of story-telling. I do terrible on literature
2. I'm busy running TMRE
3. I have lots of other work to do (250 math problems daily)
