The system is great at answering "What is X?" but falls apart when you ask, "How does X rela...
Discrete mathematics plays a key role in machine learning and algorithms. You can use it to find the shortest path (graph theory), encrypt files, compress data, and to do many other things.
We just posted a discreet mathematics course on the freeCodeCamp.org YouTube channel. Karol Kurek teaches this course. He is a former math teacher and senior Python developer.
