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.
Algebrator is simply amazing. Who knew that such an inexpensive program would make my sons grades improve so much.
I really needed help with fractions, the program listed each of the steps, so I was able to get my homework finished in time. Thanks.
