About

Purplemath, Inc is a free-access algebra-lessons web site. Purplemath's lessons were written by Elizabeth Stapel, initially for her students at Western International University, South Mountain Community College, and other Phoenix-area institutions. Ms. Stapel has created many animations which supplement the lessons and highlight and clarify difficult concepts; a particular favorite is her "hand" animation explaining how to multiply two matrices:

* How to Multiply Matrices

* "hand" graphic:

Since 1998, when Ms. Stapel created her first personal web site for her student, Purplemath has steadily grown by about 30% a year. Access to the algebra lessons remains free to site visitors, with expenses paid largely by advertising and online tutoring. The Purplemath web site contains hundreds of pages of lessons and a free homework-help forum. Some trigonometry lessons have been added, and Ms. Stapel hopes soon to start expanding into elementary calculus topics.

If you have software, services, or other resources which you would like to advertise on the Purplemath web site, please review Purplemath's advertising policies, and enquire.

    Purplemath's visitors consist generally of high-school and college students, plus homeschoolers (and their parents) and many non-traditional "returning" students. Long-term visitors tend to be self-starters; students who are willing to invest the effort necessary to master the material; students who want to understand the concepts, but who are struggling with poor textbooks, inarticulate instructors, online "education", or the long interval since having left high school. Contracted rotational advertising on Purplemath is "targetted", meaning that we do not accept porn, gambling, offshore "investing", or other off-topic or offensive campaigns. The advertiser has two options: placing a small "skyscraper" ad in the sidebar of the lessons ("content") pages, or placing a small "banner" ad within the topics of the forum pages. Each page displays only one contracted rotational ad. Skyscrapers are displayed in the right-hand sidebar of lesson pages, "above the fold" and above (or in place of) any contextual advertising on the page; your ad would not be placed on my work history, for example, or next to lists of links. Ads are rotated and served randomly, so your ad would appear, now and again, throughout a user's traversal of the site.
