This is a great textbook for Intermediate Algebra or College Algebra course. This textbook includes covers standard topics such as linear functions/equation, graphs and functions, systems of linear equations, polynomials, rational functions, roots and radicals, quadratic functions/equations, exponential and logarithmic functions, conics, and sequences and series. All of topics are self-contained and instructors do not have to provide supplements. However, instructors, who plan to cover trigonometric functions, may need to provide extra materials.
The author made a great effort in this aspect and the examples, homework problems and the solutions I read are error-free.
The content of algebra should remain the same for a long while, therefore, the book is very suitable for what are taught .As most openstax math books, the book provides very useful youtube link at end of each session, which is very appropriate for the learning habit of current students.
The author made a tremendous effort to make mathematical contents accessible to students. The first chapter Foundations provides a reference. There are lots of tables to compare similar terminologies which students may be easily confused. For example, on page 690, a table is provided to help students to understand rational expression and rational functions.
The whole book is organized in a very consistent format from chapter to chapter, and from section to section. Moreover, consistent terminology and notations are used throughout the whole book.
The book is well designed and facilitates instructors' teaching and students' learning. Each section starts with clearly stated learning objects, followed by Be Prepared! with exercises and the similar examples in previous sections, which helps students to review what they need for the current section. I have to mention, students can just click examples in blue to locate them.
The order of the topics is presented in a logical way and all examples and problems are ordered from easy to more challenging.
The links for chapters, sections and even specific examples which allow users to jump specific locations work well. Colors and headings really help reader to sort out information.
I did not spot grammar errors.
I did not spot any culturally insensitive or offensive instance.
I have adopted this as a textbook for one semester. From my experience and students' feedback, it is a user-friendly and comprehensive textbook. I will still use it in the future.
