I have been using Algebrator and it has helped a great deal. I find it very helpful as a check against my problems. I solve them manually and then use it to check my work.

It appears you have improved upon an already good program. Again my thanks, and congrats.

I really like your software. I was struggling with fractions. I had the questions and the answers but couldnt figure how to get from one to other. Your software shows how the problems are solved and that was the answer for me. Thanks.
I just wanted to tell you that I just purchased your program and it is unbelievable! Thank you so much for developing such a program. By the way, I recently sent you an email telling you that I had purchased PAT (personal algebra tutor) and am very unhappy with it.
