I just bought your program. I purchased the Personal Algebra Tutor (PAT) and I am really disappointed with it. Reasons: 1) if the computer crashes, you have to email them for a password (where I live, on a mountain with high winds, we get alot of power outages) as well as lightning strikes; 2) they said that the problems could be typed in and a solution would be provided. Half of the math problems I have had, do not work with their program; 3) they say to email them the questions and they will provide the solutions, but it can take up to 24 hours, and sometimes that is too long to wait for an answer. To show proof of my confirmed purchase of the PAT program, I have attached a copy of the receipt that they sent to me.
I bought "The Algebrator" for my daughter to help her with her 10th Grade Advanced Algebra class. Like most kids, she was getting impatient with the evolution of equations (quadratic in particular) and making mistakes in her arithmetic. I very much like the step-by-step display of your product. I think it got my daughter a better grade in the past semester.
Graduating high-school, I was one of the best math students in my class. Entering into college was humbling because suddenly I was barely average. So, my parents helped me pick out Algebrator and, within weeks, I was back again. Your program is not only great for beginners, like my younger brothers in high-school, but it helped me, as a new college student!
