The emphasis of this site is on teaching and learning and the author makes every effort to engage the student/reader in the exploration and discovery process; the level of interactivity is outstanding. Thoughtful solutions are presented and the reader is guided to an analytical understanding of the underlying mathematical principles involved. In some instances alternative solutions are presented; in others, applications to other mathematical fields are described. Altogether, this site contains a wealth of educationally effective materials. In addition, there is an annotated listing of other math resources on the internet that is quite excellent and potentially helpful to the reader.
Suitable for many different levels of user - some material is beyond the general user and requires college-level math knowledge.
The banner ads at the top of each page and the shopping links in the sidebar are relatively unobtrusive.
