    I found a good link which shows the basics of how to use the TI-84 Plus right off of the TI website. (http://hotmath.com/graphing_calculators/ti84_movie_index.html ) Besides buying a Dummies book, is there any links or such that you guys are aware of that I could look at (or project to my class) that show other things that could be really useful such as:

    "Let’s say you want to choose from a combination of 50 items and you want to choose a set of 3. To find out the number of possibilities, here is what you do.
    Type in “50”
    Math
    Push Right arrow three times (or left arrow once)
    3 for “nCr”
    Type in “3”
    Enter


    Thank you very much!
