I think this is a great piece of software. I applaud your efforts to bring a product to struggling math students such as myself.
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.
My son was always coaxing me to keep a tutor for doing algebra homework. Then, a friend of mine told me about this software 'Algebrator'. Initially, I was a bit hesitant as I was having apprehension about its lack of human interaction which usually a tutor has. However, I asked my son to give it a try. And, I was quite surprised to find that he developed liking of this software. I can not tell why as I am not from math background and I have forgotten my school algebra. But, I can see that my son is comfortable with the subject now.
Be it Step by Step explanation for an equation or graphical representation, you get it all. I just love to use this due to the flexibility it provides while studying.
