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.

The Algebrator is the perfect algebra tutor. It covers everything you need to know about algebra in an easy and comprehensive manner.

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.

Algebrator is easy to use and easy to understand and has made algebra the same for me. I am thankful that I got it.

I failed Algebra at my local community college twice before I bought Algebrator. Third time was a charm though, got a B thanks to Algebrator.
