One of the best online course i have ever taken. Thanks to Keith sir for explaining all the concepts so engagingly and in detail. Looking forward for course's like this on coursera.

This course actually changed my life. It gave me the courage to start studying mathematics at a university. Thank you so much, Dr. Keith Devlin and the team at Stanford University!

The course is a really good introduction into the world of mathematical proofs and the logic behind them. Really, everyone will benefit from the way of thinking the course teaches.

This is a very important course on the journey to mathematical mastery. It helped in developing the ability to read and write mathematical statements without feeling intimidated.

What a nice course! I like the logic, interesting and vivid process in this course. I am appreciated to the professor and I will review what I have learned in recent days.

As the name suggests, it is a great introduction to the world of mathematics. No unecessary pressure, which makes it an enjoyable experience for those willing to learn.

Hard work but worth it. I get the feeling I now know something about what maths is about.

Brilliant teacher, although I didn't realize this until completing the course.

Great course. Really teaches you how to think. If you are making the transition to college mathematics. I would highly recommend this course. It could not get better>

great course that make you able to establish proofs and use mathematical notations also it help you in some branches of math like number theory and real analysis.

Only one word: Brilliant.

Take this course if are aiming to become a Mathematician. You will not regret it. It's absolutely must for all who are entering college.

A lot of much time spent on simple things and no enough example with answers to make sure we understand the exercise. (sorry no precise example available handy)

This course convinced me of enrolling for a college degree in mathematics, I don't think I can say much more. Thanks to professor Devlin for this amazing work.

Very dedicated teacher. Very clear and neat teaching method.

The teacher solves a lot of good examples by himself and this makes the course very understandable.

Sometimes challenging, but very interesting and fascinating course! Keith Devlin is a talented professor and his way of describing topics is well-constructed.

Wonderful Course. A great distraction from the Covid19 virus. Much more interesting and exciting than Netflix. Thankyou to all involved in its creation.

It's a pretty good course. I learnt a lot. I hope Stanford open more math courses in math field, such as Number Theory, Analysis, and Abstract Algebra.

Es un curso muy bien orientado, y el método de enseñanza es excelente. El profesor te enseña a pensar más allá, lo recomiendo para todos los niveles.

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！

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...

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

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

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

Thanks for the extraordinary amazing course!

Especially for sharing your passion for math with us!

I just loved studying these weeks!
