Algebrator is far less expensive then my old math tutor, and much more effective.
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.
I like the ability to show all, some, or none of the steps. Sometimes I need to cross reference my work, and other times I just need to check the solution. I also like how an explanation can be shown for each step. That helps learn the functions of each different method for solving.
