It appears you have improved upon an already good program. Again my thanks, and congrats.
Candida Barny, MT

I really needed a way to get help with my homework when I wasn't able to speak with my teacher. Algebrator really solved my problem :)
Pam Marris, TX

Just when I thought I couldn't find the program to do the job, I found Algebrator and my algebra problems were gone! Thank you.
C.K., Delaware

I just wanted to first say your algebra program is awesome! It really helped me it my class! I was really worried about my Algebra class and the step through solving really increased my understanding of Algebra and allowed me to cross check my work and pointed out where I went wrong during my solutions. Thanks!
Lori Barker

Keep up the good work Algebrator staff! Thanks!
