Comments from students:

Linear Algebra website ROCKS!!!!!!!!! THANK YOU!
If I had only found it 2 months ago, I would have aced the course.

I just wanted to thank you for your Linear Algebra Toolkit. I am a student at the University of North Texas, and have had trouble understanding a few things in linear algebra. Your Linear Algebra Toolkit has helped me.

I love your Algebra Toolkit!  Very well laid-out, easy to navigate and very effective.

Great site! It's helping me a lot with span, nullspace, and basis. Thanks.

Hi, just a note of appreciation. I am a mature student taking a linear algebra class (have been out of high school for 20+ years). I found your site very helpful in checking my work. Great Site!!!

Comments from instructors:

Thank you for permission to use your software. This will be very helpful to my Finite Math Students outside of class in checking both their process and arithmetic for the Gauss-Jordan Method.
Terry Boyd, Instructor, University of Indianapolis
Fantastic!!! Several years ago I wanted to build a similar tool, but I did not know how to do it.
Juan Manuel de Olazabal, Departamento de Matematicas, Universidad de Cantabria, Spain
I am teaching a Finite Math class for the Colordo Community Colleges Online. One of my students found your site and was quite impressed. I would like to share it with the rest of my class as well as with the teacher of our Linear Algebra class [...]. Thank you for all the work that you have put into this.
Mary Sloan, Math Dept, Arapahoe Community College, Littleton, CO
I am going to use the "Linear Algebra Toolkit" in my classroom where I am teaching a Linear Algebra course this semester. I find that your toolkit is very helpful for my students as well as myself.
Great thanks for your excellent work.

Thank you for letting us use your modules. I demonstrated the concepts in class and showed the students how they could use the Systems of Linear Equations and Matrices modules to help solve the systems. I especially liked the row operation calculator as it helped the students see each individual step along the way to solving a linear system.
