The TI 86 is a little harder to learn to use than the TI 83.  It has a setup very similar to that of a computer.  The function keys F1 through F5 on the top of the calculator face are primarily used to choose menu options.  In the bottom right corner of the face are the arithmetic keys.  Graphing calculators are different from scientific calculators in that instead of using an "=" key, the enter key is used.  Pressing enter usually brings finality to an operation or function.  To maneuver the site, use the buttons at the top or bottom of the pages.  If you have any feedback whether it be questions or comments, use the feedback button at the top of the page or email me at dottie.walton@tri-c.cc.oh.us.  Once completing the entire tutorial, you should consider yourself as an intermediate/advanced user.

When going through the site, if you get to a point and are ready to start some practice problems, return to the top of the page to navigate to pages on that same level.  Parent level pages can be navigated at the bottom of the pages.  At the extreme top of the pages is the top level navigation.
