Students struggling with all kinds of algebra problems find out that our software is a life-saver. I am so far quite pleased with the program Brittany Peters, NC This version of your algebra software is absolutely great! Thank you so much! It has helped me tremendously. As a parent, I am delighted, because now there are no more late nights having to help the kids with their math for me. One of the best features of this program is the ability to see as many or as few steps in a problem as the child needs to get it. I purchased your software to help my daughter with her algebra homework, the Algebrator software was very easy to understand and it really took a big burden off. He now takes a lot of interest in fractions and exponential expressions. My decision to buy "The Algebrator" for my son to assist him in algebra homework is proving to be a wonderful choice.
