Mathematical concepts are sometimes difficult to understand as we enter the world high school and college level math. This website makes understanding those concepts by giving a animated visual representation of the mathematical concept. The videos are simple and show the equation along with the visual representation. The downside is there is no detailed information or explanation. So using the site with students that do not already have an understanding of the concept, or without a teacher further explaining the concepts it is of little use.
