A perennial bestseller by eminent mathematician G. Polya, How to Solve It will show anyone in any field how to think straight. In lucid and appealing prose, Polya reveals how the mathematical method of demonstrating a proof or finding an unknown can be of help in attacking any problem that can be reasoned out--from building a bridge to winning a game of anagrams.

This book contains no magic, no tricks. It's not one of those "esoteric knowledge revealed" books nor a book which promises you'll get an Abel prize or a Fields Medal someday.
What this books is, is a systematic and incredibly instructive overview of guidelines in mathematical problem solving, which are, as the author put it - "natural, simple, obvious, and proceed from plain common sense."

George Polya's classic How to Solve It is a seminal work in mathematics education. Written in 1945 and referenced in almost every math education text related to problem solving I've ever read, this book is a short exploration of the general heuristic for solving mathematical problems. While the writing is a bit clunky (Polya was a mathematician and English was not his first language), the ideas are so deeply useful that they continue to have relevance not just for solving mathematical problems,

Polya tries to explain how to become a better 'problem solver', and how to guide others to better solve problems themselves. The core of the content is terrific, and gets you thinking about 'how to best think'.
Unfortunately, almost everything gets repeated numerous times, and as a whole the books ends up being thoroughly redundant. You don't really need to read beyond the first 36 pages (the rest of the book consists of a 'problem solving dictionary', and here's where the redundancy begins).

This is a book I wish I had read at the beginning of grad school. How to Solve It is not as much about methods of solving mathematical problems as it is about various approaches to solving problems in general. The method he uses to teach problem solving is to apply the approaches to problems of geometry. This is actually in line with the ancient greek (Aristotle) opinion that the young should learn geometry first, then when they have learned logic and how to prove things with physical reality, t

This is one of those mathematical "classics" that those of us with a training in math are supposed to love. Fact of the matter is that it is poorly written and pedestrian in nature. If you are seeking insight into how mathematicians think and approach problem-solving, give this one a miss. You'd be far better off to read Hardy's "A Mathematician's Apology" (dated, but still charming), or Ian Stewart's recent "Letters to a Mathematician" (charming and not dated at all).
I recently finished reading How To Solve It - A New Aspect Of Mathematical Method - by George Polya.
Below are key excerpts from this book that I found particularly insightful:
A great discovery solves a great problem but there is a grain of discovery in the solution of any problem. Your problem may be modest; but if it challenges your curiosity and brings into play your inventive faculties, and if you solve it by your own means, you may experience the tension and enjoy the triumph of discovery. ...more

Pólya is the teacher I never had.
Now you might get scared with the word "Mathematical" in the title - don't be. It is a general guide to how to solve a problem. Starting from establishing the question, gathering the known and to find the unknown. The method you are using to find the minimum distance between two points can also be used to find the most convenient road to your nearest grocery store. This book shows you -"How to Solve it".

One of the most useful books I've read in my life.
It's an authentic treasure to everyone interested in problem-solving (and every one of us has enough problems to be interested in with problem-solving).
I think this should be one of the obligatory lectures for high-school or college education because it states clearly the steps one intuitively follows when trying to solve a problem mathematical or not.
The key takeaways for me are:

This book was used as a reference in several of the other books I have read, and I understood it to be more of a general methodology of problem solving when I decided to read it. It is written in a somewhat awkward style, to an audience that is difficult to discern, and with enough repetition that I had to skip pages at a time to get to the next topic. This was frustrating as I really wanted to like this book. When Polya does focus on the generalized concepts of problem solving, he has wonderful

This is a great book.
It teaches solving mathematical problems. It is mostly focused on high-school problems, but it is applicable to most types of mathematical problems out there. The author has developed a nice heuristic framework for tackling problems and has done a wonderful job of explaining it. It's not just the methods – exposition is also a great takeaway from this read.
On the downside, the book was written in 1945 and sometime it shows. It's more cute than a nuisance, though :)

This is such a great book. Polya lays out the different approaches you can take to solve a problem. He primarily uses Euclidean geometry to explain the possible ways to approach different problems.
This is especially great when you have to analyze a problem that you haven't seen before - where and how to begin? He goes through the problem-solving process in detail, beginning with the detailed analysis of the question and then the systematic synthesis of the answer.

The book, written in 1950, still applies today and attempts to find a method to discover the solution to any mathematical problem we may encounter in our life. Although sometimes repetitive, the author is very pedagogical and presents various examples to illustrate his method. Despite the fact the examples are mainly on the Math field, he manages to translate them into other domains (like engineering, physics, psychology, etc.). A book nice to have in our library :)
I'm conflicted about this book. There is a lot of good advice around the art of problem solving, but my god is there a lot of shit too. The layout is mostly a big alphabetical glossary of _math things_ --- everything from leading questions to notions of symmetry to anecdotes about absentminded professors --- and the layout doesn't particularly help. It's not organized by topic or ordered by first things first, it's just plopped down alphabetically. As such, it's hard to get into the flow.

How to Solve It is basically a +1 intelligence potion bottled in a math text. I read this book one rainy day and it boosted my ability to creatively problem solve thereafter. It's not that you won't stumble upon Polya's methods on your own, but rather this book saves you the time and gives you a foundational rubric for many types of problems. It's worth reading no matter your background.

You have to understand the problem.
UNDERSTANDING THE PROBLEM
What is the unknown? What are the data? What is the condition?
Is it possible to satisfy the condition? Is the condition sufficient to determine the unknown? Or is it insufficient? Or redundant? Or contradictory?
Draw a figure. Introduce suitable notation.
Separate the various parts of the condition. Can you write them down?

On the surface How to Solve It by George Pólya is a short little book about strategies of solving mathematical problems. Deep down, however, it is not a book about mathematics, but it's a book devoted to heuristic - the study of methods and rules of discovery and invention.

Elegance in solving problems is not strictly a mathematical skill set. Polya wisely formats word problems, critical thinking problems, and yes mathematical problems that occasionally are intimidating.
But one of the big takeaways is that problems are only as hard as they are unresolved. Not only does Polya give excellent ideas for solving problems: creating auxiliary problems, using heuristics, working backwards.
Each example that Polya gives takes concentration and critical analysis. But when yo ...more

This is a cool book. It's a comparatively rare thing for a first-class mathematician to write really seriously and thoughtfully about math education; at least it's not something I've come across too much. And it's been about a year and a half since I read anything about math education I didn't feel like I already knew. (Props to the _Young Mathematicians at Work_ series by Fosnot and Dolk, which was the last thing I read like that...)

I don't remember when I first encountered this book -- I think it was early in my time at Cornell. It's had a great deal of influence on how I approach math. It's one of the best math books I've ever read, and quite possibly the best book on mathematical problem solving ever written.
There are two copies of it floating around my lab at Berkeley, evidence, i think, that I'm not the only one who appreciates it.

For the most part, I enjoyed the book. I liked the way it was written. However, some of the math examples were completely above my level of comprehension, and I had to bribe myself to read through those droll parts to understand what the author was trying to illustrate rather than just skipping. I had to read the book twice, because I kept "checking out" after those droll parts, but the second time I read it, the concepts it was trying to teach really started clicking.

I picked this up by happenstance in a college bookstore over the summer. I'm always looking for educational texts on analytical methods, so this one caught my eye. What an amazing find! Pólya presents the reader with a list of steps to use when analyzing a problem and breaks each one down comprehensively. The entire book references back upon itself repeatedly, so you can always circle back to important, related points.

Hailed as the classic guide to problem solving, this book did quite a good job at categorizing the ways of looking at a problem, and some general methods of solving and treating them. However, I think I read this at the wrong time - it could have fascinated me much more had I read it in the early 2000s (then again, there was not any translation to Vietnamese back then, and I suspect my mediocre English back then would not let me finish it).

How To Solve It contains a collection of heuristics intended to get you unstuck when solving difficult problems. It’s mostly intended for mathematical problems, but there are some examples taken from solving crosswords, chess, and even primitive man trying to cross a river.
