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.
This new version is a vast improvement over the old one.
Ive been a high-school math teacher for over sixteen years and luckily, Ive had computers aiding me in the classroom since the Apple II. But nothing has ever gotten the results or helped my students understand as many advanced equations and concepts as Algebrator has! Thats why nowadays, I make sure every student system in the school (even the notebooks) are running it! If nothing else, it makes our jobs a lot easier!
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.
