    TI's are pretty universal. If you look under the Calc menu which should be above trace (hence 2nd trace), you should find the intersect function as the 5th option.

    Just did a google search and it looks like the 86 is a bit different. You might try this link:

    That reminds me of the TI-89 solver. You type the info into the TI-89 in much the same manner. Very nice. Too bad you can't be connected to the internet during the AP test!

    My kids are using the TI-83 plus and that doesn't have the solver. We're stuck using the graphical approach that I posted earlier.

    It's a very neat site. It's more than a calculator, too. Try writing "What is the unemployment rate of females in the United States?"
