I'm trying to find a place that has guided walkthroughs/answer guides for intermediate algebra, college algebra, and precalc. Maybe trig, also. Any ideas?

I have found good results at www.khanacademy.org. You can sign up for an account, watch tutorials, practice exercises in a pedagogical order, and track your progress. Another site that has a lot of good walkthroughs is www.patrickjmt.com, but without the exercises. Best wishes.

    $\begingroup$ Great. It seems to be free, too. Sorry, but I can't accept for 6 minutes. Maybe we'll get another good site. :D $\endgroup$

  • $\begingroup$ I really need to do that, too. As I got into Calculus 3, I realized my ability with Algebra was declining rapidly. I was still pretty good with Trig, though. Now, I'm out of practice with Trig as well. I feel like I don't have time to plan lessons for myself, and I hope that these sites will keep my mind up to date, as I study new things, like programming. $\endgroup$

  • $\begingroup$ I agree with you, @FreeTrader. Although we must be happy with what there is! $\endgroup$

I think Art of Problem Solving is a good place to get several Questions on algebra or what ever topic you want in various levels of difficulties. Art of Problem Solving Website : http://www.artofproblemsolving.com

dzdx.xyz contains algebra exercises on

  • factorization of polynomials
  • simplification of rational fractions and expression with radicals
  • logarithmic identities

I'm working through a book titled "The Humongous Book of Algebra Problems". It primarily covers Alegbra I and II. Over 1,000 problems to work through. So far I've found it quite good.
