What factors should you consider when choosing a math textbook for self-study?

Choosing the right math textbook can be daunting with so many options on the market. It’s important to consider various factors, such as the author’s credentials, the clarity of explanations, and the layout of problems. Some friends of mine swear by popular series, while others prefer niche books that dive deep into specific topics.

A well-balanced textbook should combine thoroughness with easy-to-follow steps, especially if you benefit from a gradual breakdown of complex concepts. Have you found any particular textbooks helpful in your own learning? What tips can you share for narrowing down your choices?
