This textbook, winner of the 2018 Digital Learning Innovation Award from the Online Learning Consortium, was developed by the mathematics faculty at Portland Community College under the direction of Alex Jordan and Ann Cary with careful attention to accessibility issues. It has been class tested there and is being used elsewhere. The book is offered in three formats: online HTML (or eBook), PDF, and print. The versions are essentially identical, but the eBook version has features unavailable in the other versions such as the video lessons and checkpoint problems with boxes for the student to enter answers and submit them for checking (not grading). In the PDF and print versions the checkpoint problems are followed by worked out solutions.

The various versions are all produced from the same source files written in PreTeXt.
