I purchased the Personal Algebra Tutor (PAT). The system is not has functional as I wanted or expected, and there are several problems it will not solve, or certain problems will freeze up the system. The program is OK but there are too many limitations and several technical issues. It took three e-mail from their tech support just to activate the program.
If anybody needs algebra help, I highly recommend 'Algebrator'. My son had used it and he has shown tremendous improvement in this subject.

Great stuff! As I was doing an Internet search on effective math software, I came across the Algebrator Web site. I decided to purchase the software after seeing the online demo and never regretted it. Thanks!
