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.

As a teacher I praise Algebrator because the students love it and find it most stimulating and interesting. What they see is what they learn and moreover it is relevant to the curriculum.
