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.

My math professor suggested I use your Algebrator product to help me learn the quadratic equations, and non-linear inequalities, since I just could not follow what he was teaching. I was very skeptical at first, but when I started to understand how to enter the equations, I was amazed with the solution process your software provides. I tell everyone in my class that has problems to purchase your product.

As a user of both Algebrator 2.0 and 3.0 I have to say that the difference is incredible. I found the old Algebrator useful, but it was really difficult to enter more complex expression. With your new WYSIWYG interface that problem has been completely eliminated! It's like Word Equation Editor, just simpler. Also, thank you for not using the new new software as an excuse to jack up the price.

Thanks so much for the explanation to help solve the problems so I could understand the concept. I appreciate your time and effort.
