We are a Los Gatos based company that focuses on web-native animated, interactive learning for STEM subjects. That being said, we offer a coursebook on Discrete Mathematics (and other STEM subjects) that is developed online and provides problem-oriented learning, examples, and interactive animations. It's our goal to effective encourage learning in STEM and to provide useful, helpful examples to individuals who make use of our materials. Anyway, check us out at www.zyante.com And good luck!
