Thanks to Prof. Keith Devlin. This course is a must for everyone planning to undertake an undergraduate program in any field related to mathematics.

很棒的数学课程，适合大学新生在上高等数学时学习。这门课详细介绍了数学证明的方法，并且会告你大学学的数学和高中时不一样，最后一周的互评作业也很有意思，通过批改其他学生的作业我也学到了更多知识。这门课让我对数学有了更大的兴趣，如果你对数学感兴趣或者想学好大学数学的话，你应该来试一下这门课程！

Amazing subject with excellency in explaining. Widens our thinking process over the subject & general life. Loved that I finished this course.

You don't learn math only; you learn the techniques of logical reasoning.

This course is evaluable and helps me become a more effective thinker.

Such a delight having followed this course... it was a real pleasure to think differently other than usual... thinking mathematical for once...

Τhe lecturer of the course is quite explanatory. The course material is quite well organized with methodical steps in explaining the concepts.

Great lectures that broke down intimidating concepts to be understood easily. I already feel the impact on my thinking. Thank you Professor!

curso muy bueno, muy desafiante para el pensamiento y para cambiar la perspectiva de lo que ya tenemos aprendido previamente. recomendable.

very good course to learn mathematical reasoning. You miss many important points when you are a graduate and have lot of material to study.

I'm from Indonesia. This course is very good. I think this course is great for those who want to understand how mathematical proofs work.

Considering the world and media's regressive subjectivity, this course will realign your mental spine with some good old-fashioned Reason.

Dr. Devlin is very passionate about mathematics and it comes through in his teaching. This is a great course overall and very challenging.

It is a nice course to learn how mathematicians write proofs. Also how to think in logical way. Great course for maths enthusiasts like me

recommended to anyone who wants to seriously start discovering this fascinating world. Mathematics is the distillation of human knowledge

The course had generally taught me things that are not mathematics but the fundamentals of it and I like that is more important overall.

best professor i every seen and this course introduction to mathematical thinking is perfect for those whose loves magic of mathematics .

Excelente curso y el profesor muy dedicado y explica de una manera muy amena los diferentes temas. Me gusto mucho el curso. Mil gracias.

The precision and elegance of Mathematical thinking is realised in this course - the Essence without the intimidation of the subject

It was my first experience with coursera. Thanks to Keith Devlin and Stanford University and corsera.org for providing this course.

Amazing course for learning the basics of mathematics and induce mathematical thinking which is base for many higher level courses.

Thanks for the extraordinary amazing course!

Especially for sharing your passion for math with us!

I just loved studying these weeks!

I'm sure that I will come back to this course! Thank you very much Profesor Devlin! You are a great teacher! Greeteing from Poland!

I think I learned some math ;). Great and in-depth content. Although (unsolved) technical issues with downloading the assignments.

This was a really helpful course because it mainly focused on the basic concepts that is to be understood necessarily. Thank you.

Really beautiful course. This one finally got me out of the "I can not read and understand mathematical notation" bandwagon!! :-)
