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 was having problems learning quadratic equations, until I purchased your software. Now I know how to do not only do quadratics, but I also learned with the step by step examples how to do other more difficult equations and inequalities. Great product!

I was quite frustrated with handling complex numbers. After using this software, I am quite comfortable with it. Complex numbers are no more 'COMPLEX' to me.

My decision to buy "The Algebrator" for my son to assist him in algebra homework is proving to be a wonderful choice. He now takes a lot of interest in fractions and exponential expressions. For this improvement I thank you.
