About Michael Eiseman
I am a chemical engineer with 30 years' experience in the chemical industry. For the past several years I have been volunteer tutoring A Better Chance high school scholars. I noticed that I could perform algebra much more quickly than my students and determined why my mental processes lead to faster solutions.
In the United States we are taught to solve algebra problems by applying equivalent operations to both sides of an equation. I realized that I had stopped doing algebra this way long ago. Instead, like most experienced mathematicians, I was moving terms and factors in my head − a much faster and easier-to-visualize method. The most effective way I could think of to share my mental processes with my students was to build Algebra By Hand™. And now I'm sharing it with you as well − for free!
Algebra By Hand is based in Swarthmore, Pennsylvania.
