One of my students brought in a program called Algebrator. At first I thought it would be a great tool to help all my students who were struggling. When I researched further, I figured out that it also helps me prepare a lesson in half the time.

My fourteen year-old son, Bradley, was considered at-risk by his school. But, I couldnt make him listen to me. Then when a teacher at his school, Mr. Kindler bless his heart, got him to try an after-school program, it was like a miracle! I wouldnt say Bradley became a model student but he was no longer failing his math classes. So when I found out that Mr. Kindler based his entire program on using Algebrator, I just had to write this letter to say Thank You! Imagine that!

My son has used Algebrator through his high-school, and it seems he will be taking it to college as well (thanks for the free update, by the way). I really like the fact that I can depend on your company to constantly improve the software, rather than just making the sale and forgetting about the customers.
