When you go to university, you are required to purchase many math textbooks that are sold extremely expensive. Since your instructors mostly do not offer free math textbooks, they become a huge burden for almost every student and parent. However, you do not need to worry about that problem anymore!
Today, there are so many open-source projects that provide free textbooks for college students and instructors. Open Textbook Library is one of them! Moreover, they are written by knowledgeable scholars.
