MathNotes currently offers two new resources to help you strengthen your understanding of the mathematics you are studying: InterAct Math software tutorials and Numbers in the Real World Web problems.

InterAct Math is an interactive tutorial that allows you to work through an infinite number of problems with hints and guided solutions. InterAct software (the InterAct plug-in) can be downloaded from this site so that you can sample the math problems using your Web browser.

Numbers in the Real World applications are exploration exercises that build upon the real-world uses of math discussed in the textbook. Many of these problems require you to visit and collect data from external Web sites.

See the Numbers in the Real World Index for a complete listing of Real World application exercises.
