For self-studying Discrete Math, several book recommendations emerged in the discussion. A free online resource was shared, which offers a comprehensive introduction to the subject. One participant mentioned their previous struggles with the class but expressed a renewed interest in the material. They emphasized a preference for physical books over digital formats for better engagement and highlighted the desire for application-focused content. A specific book by Kenneth Rosen, "Discrete Mathematics and its Applications," was noted for providing essential tools for understanding the material, though its effectiveness was questioned. Another recommended text was Ralph P. Grimaldi's "Discrete and Combinatorial Mathematics," praised for its comprehensiveness and additional study resources. Overall, the conversation highlighted a mix of personal experiences with Discrete Math and a quest for effective study materials.
