Wow, what a great mathematical resource! I already bookmarked this page because it looks like if i need any kind of help in math or arithmetic in the future, this sure will be the resource that i will use. The best thing about this website is that it offers many Java based animations that really help understand the concepts. It also offers quite a few problems so you can do those and check yourself at the end, including many hints provided. I spent about 15 minutes going through the Statistics section, and this site definitely appealed to me since i will be taking statistics in the future. Outstanding mathematical resource, would definitely recommend it!
