Welcome to the “Mathematics for Machine Learning and Data Science” blog post series. The information contained in these posts will give you the necessary mathematical grounding in linear algebra, calculus, and statistics for a successful career in data science or machine learning. This guide is intended to be a roadmap for learning the math, and as a reference to quickly lookup and acquire mathematical background knowledge for solving concrete problems. For an in-depth guide to the math, you need to succeed in machine learning, check out my post on what math is required for machine learning.

I hope this guide will make the math for becoming a data scientist less intimidating.
