Elementary Algebra is designed to meet the scope and sequence requirements of a one-semester elementary algebra course. The book’s organization makes it easy to adapt to a variety of course syllabi. The text expands on the fundamental concepts of algebra while addressing the needs of students with diverse backgrounds and learning styles. Each topic builds upon previously developed material to demonstrate the cohesiveness and structure of mathematics.
I'm using this series of OpenStax math books to reteach myself the math I used to know. It's well organized, the coverage is good, and it has plenty of exercises and example, but I hesitate to recommend it because I kept running into examples and exercises where the book gave the wrong solution. I know it sounds like I was probably just doing the math wrong, but I checked several of them on Wolfram Alpha to make sure I wasn't going crazy, and in several cases--maybe once or twice per chapter?--the book was wrong. They definitely need to proofread it more carefully. That said, I felt like I learned what I set out to learn, and of course the price was right.
I relearned a lot and I appreciate that there are many practice examples. I actually found it more useful than khan academy. The videos from KA are nice for a (somewhat) deep dive into a topic, even basic ones which schools never have time to do, but doing lots of examples helps to lock things into memory.
