OpenlySolved is a digital library of living documents (living documents are documents that are continuously being edited and refined) containing fully-worked solutions to problems found in commonly used mathematics textbooks in Singapore. This means that many of the documents you see are work-in-progress. It also means that you should download the documents only when you need to use them. That way, you'll always get the most updated version.
Conventional textbooks typically provide only the final answers to the problems. While these answers are useful for the better students, who can use them for verifying that their own answer is correct, they are not helpful for the weaker students who may not even know how to begin solving some of the questions. These students need help learning mathematics on their own, and what is useful is the detailed solution process, not merely the final answer. This is what the solutions in OpenlySolved provide - the detailed steps involved in solving each problem - not merely the final answer - all at no cost. Register (for free) to access the solutions and to discuss the topics.
OpenlySolved is also a community of people that use textbooks. It is hoped that the members of this community will get together in the forum to discuss the solutions, highlight any errors in the textbook, and help one another learn. Although some initial solutions have been provided, it is hoped that the community will solve the remaining questions, and make the solutions available to all the other members.
OpenlySolved is currently looking for moderators who can “champion”the complete solution of all the questions from a textbook of their choice. If you wish to volunteer as a moderator, please email me at firstname.lastname@example.org. Lastly, online safety is important all forumers. Please read the online safety tips compiled by the FBI before participating in discussions.
Lee Chu Keong,
P.S. Who am I? I am a lecturer at the Nanyang Technological University. I am grateful for what I make through teaching, speaking and training. It is enough.
