Doing math means making a lot of mistakes. It is inevitable. However, you should learn from your mistakes so as not to repeat them. Follow this simple advice, and you will be far more successful with your study of mathematics.

Below are some online tutorial websites to help you avoid making the same mistakes twice. They are grouped according to subject. Enjoy.

**GENERAL ARTICLES ON MATHEMATICS**

** **WHO’S COUNTING – This is a great link from ABC News. This site contains countless articles written by Temple University mathematics professor John Allen Paulos (author of many books including his most famous, “Innumeracy.”) What’s nice about these articles is that they are entertaining, informative and written at a level that allows anyone to understand them. DANGER: if you are not careful, you may spend hours reading these articles!

THE MAA MATHEMATICAL SCIENCES DIGITAL LIBRARY – This web site is just what it says. It is a large digital library created by the MAA. You can find links to such things as mathematical articles, MAA book reviews, *Loci*: the online publication of the MAA, and pdf copies of articles that have won MAA writing awards. However, the best part of the library is the “ON THIS DAY” section. Learn about things that happened “on this day” in mathematical history. You can even pick the day you want to look at … including events on your birthday!

**ALL TYPES OF MATH**

MATHWORLD – This is probably the single greatest website on mathematics. It is basically a mathematical library containing detailed articles on topics in every branch of mathematics.

YOURTEACHER.COM – This is an interesting video-based website. It contains links to various mathematical subjects from Pre-Algebra to Geometry as well as some college math courses. If you click on a course, you will be presented with a list of topics in that course. Click on a topic and you will get a brief video explaining the topic. If you pay a subscription fee, you will have greater access to the video lessons.

SHODOR – This is an incredible website from SHODOR: A National Resource for Computational Science Education. It contains applets and activities for an enormous amount of mathematical topics. Topics include all the standards plus fractals, graph generators, the Monty Hall problem, Buffon’s Needle and cellular automata.

GRAPHING CALCULATORS (TI-83/84) – This is a great site to help you with your graphing calculator. Calculator procedures are listed by topic. Once a topic is selected, you have explanations and screenshots to help you. Or, if you prefer, there are animations to walk you through each procedure. It is VERY helpful!
