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.
Although I have always been good at math, I use the Algebrator to make sure my algebra homework is correct. I find the software to be very user friendly. Im sure I will be using it when I start college in about one year.
It was hard for me to sit with my son and helping him with his math homework after a long day at office. Even he could not concentrate. Finally we got him this software and it seems we found a permanent solution. I am grateful that we found it.
Keep up the good work Algebrator staff! Thanks!
