Purplemath?

that is certainly a very interesting name to give to a math site. however, despite it's interesting name, i think it is a very good site. the main page is set up very nicely, and it is easy to locate exactly what you need to find help on. I searched something that i have some trouble in, distance and speed word problems. i found a very nice tutorial ( http://www.purplemath.com/modules/distance.htm ) that helped a lot. they way they explain it, and go through a problem was easy to follow, and not difficult to understand what they were doing, and how they did it. the only thing that i didn't like as much was how everything was shown in charts, when I think it would have been a bit easier to understand if they explained it a little different, or did not use so many charts at least. but besides that, i think that how they solved it, and worked through it made sense.
