100+ Useful Free Math Textbooks for Lifelong Learners

100+ Useful Free Math Textbooks for Lifelong Learners@3x

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.

100+ Free Math Textbooks…

Below, I have curated more than 100 free math textbooks for you! I even designed a fancy book cover for them. All you need to do is find a topic that interests you and downloads a free PDF copy of those books. You can purchase them on Amazon if you want to support the authors.

If you need more free sources, you should check out The Collected Papers of Albert Einstein: 15 Beautiful Physics Books.

The language and common mathematical proving techniques are introduced in this work. It serves as a transition from the computational courses (such as calculus or differential equations) that first-year college students normally take to a more abstract perspective. It lays the groundwork for more theoretical courses like topology, analysis, and abstract algebra. There is essentially no prerequisite other than a...
This book is meant to assist candidates in getting ready for admission exams in math and science, including STEP (Sixth Term Examination Paper). The Cambridge colleges base their conditional offers on the STEP exam. Warwick University also uses them, and many other mathematics departments advise their applicants to prepare for the previous exams even if they decide not to take...
I intend this book to be, firstly, an introduction to calculus based on the hyperreal number system. In other words, I will use infinitesimal and infinite numbers freely. Just as most beginning calculus books provide no logical justification for the real number system, I will provide none for the hyperreals. The reader interested in questions of foundations should consult books...
This text is intended for a brief introductory course in plane geometry. It covers the topics from elementary geometry, most likely required for more advanced mathematics courses. The only prerequisite is a semester of algebra. The emphasis is on applying basic geometric principles to the numerical solution of problems. For this purpose, the number of theorems and definitions is kept...

Teaching Mathematics at Secondary Level

Teaching Mathematics is nothing less than a mathematical manifesto. Arising in response to a limited National Curriculum, and engaged with secondary schooling for those aged 11 ̶ 14 (Key Stage 3) in particular, this handbook for teachers will help them broaden and enrich their students’ mathematical education. It avoids specifying how to teach and focuses instead on the central principles...
This textbook covers the calculus of a single variable, suitable for a year-long (or two-semester) course. Chapters 1-5 cover Calculus I, while Chapters 6-9 cover Calculus II. The book is designed for students who have completed courses in high-school algebra, geometry, and trigonometry. Though designed for college students, it could also be used in high schools. The traditional topics are...
