About this app

Algebra and Trigonometry provides a comprehensive and multi-layered exploration of algebraic principles. The text is suitable for a typical introductory algebra course, and was
developed to be used flexibly. While the breadth of topics may go beyond what an instructor would cover, the modular approach and the richness of content ensures that the app meets the needs of a variety of programs.

Algebra and Trigonometry guides and supports students with differing levels of preparation and experience with mathematics. Ideas are presented as clearly as possible, and progress to more complex understandings with considerable reinforcement along the way. A wealth of examples—usually several dozen per chapter—offer detailed, conceptual explanations, in order to build in students a strong, cumulative foundation in the material before asking them to apply what they’ve learned.

Coverage and Scope
In determining the concepts, skills, and topics to cover, we engaged dozens of highly experienced instructors with a range of student audiences. The resulting scope and sequence proceeds logically while allowing for a significant amount of flexibility
in instruction.

Unit 1 and 2 provide both a review and foundation for study of Functions that begins in Unit 3. The authors recognize that while some institutions may find this material a prerequisite, other institutions have told us that they have a cohort that need the prerequisite skills built into the course.

Lessons are great but flashcards are delaying to show up. Figures at the lessons are delaying to show up. Some of the flashcards and their back side shows [Math Processing Error]. This issue is frustrating. I would like to reduce my score from 4 to 2 or 3; because when lessons are passed Math Processing Errors are increased. That means the lesson is not readable and understandable. Are you planning to fix this bug??? SINCE the first comment, there is no improvement.

Potential is there but ads killed that. If the ads weren't so perversion, invasive, and persistently obnoxious this could be an excellent app to study with, however I hesitate to pay money for an app at all when my initial experience has driven me to uninstall it on principle. Developers screenshots are not entirely honest and should demonstrate the persistent top banner flickering around some inane products and the full screen interruption of attention every other lesson.

I'm getting [Math Processing Error] on every lesson I look at. Also it would be nice if there was a night mode or maybe a quick setting to invert colors, also it would be nice if the top bar wasn't always visible.
