Mathematics for Data Science

Learning the theoretical background for data science or machine learning can be a daunting experience, as it involves multiple fields of mathematics and a long list of online resources. In this piece, my goal is to suggest resources to build the mathematical background necessary to get up and running in data science practical/research work. These suggestions are derived from my own experience in the data science field and following up with the latest resources suggested by the community. However, suppose you are a beginner in machine learning and looking to get a job in the industry. In that case, I don't recommend studying all the math before starting to do actual practical work.
