I love the simplicity and clarity of the text. This is the way math textbooks should be written. But I really take issue with the typos and inconsistent notation used throughout this book. Hence why I'm deducting a star.
The presentation of concepts in this book is wonderfully free of unnecessary details, making it a great choice for a course textbook / main reference, but the amount of mistakes particularly in the example questions is not helpful for students who use this text to learn new materials.
