I got 95% on my college Algebra midterm which boosted my grade back up to an A. I was down to a C and worried when I found your software. I credit your program for most of what I learned. Thanks for the quick reply.

Thanks for making my life a whole lot easier!

I decided to home school my children at a young age. Once they were older, I quickly realized that I was not able to create efficient math lesson plans before I did not have the knowledge to do so. Algebrator not only allowed me to teach my children algebra, but it also refreshed my knowledge as well. Thank you for creating sure a wonderful program!

Algebrator is far less expensive then my old math tutor, and much more effective.
