I might have been a mathematician.

Reviewed in the United States on October 22, 2018

If I had been given the insights provided by this intuitive approach to math as a child it might have changed the direction of my life. Providing a framework which someone can hook the concepts of math and then fill in the details seems, at least for me, the way to to make math “stick” and see the value of learning it.

The one caveat I would add is that it would help if you have had the experience of trying to learn the concepts the traditional (confusing) way first. I never had the pleasure (insert ironic humor) of trying to learn calculus, so I needed to wrap my head are why anyone would need to learn it in the first place, intuitively or not.

That being said, if you are interested in demystifying all those formulas you’ve long since forgotten, I would highly recommend this book.

Ideal for math enthusiasts and for math/science-oriented middle/high schoolers

Reviewed in the United States on December 4, 2019

Verified Purchase

A good and fun book to learn about the intuition behind common math concepts such as logarithm, Euler's number / Napier's constant, Euler's formula, imaginary numbers, and growth rates. If this book is the first serving of these topics, then the reader should be ready to work out calculations on pen and paper to grok the intuition behind the topics. If not, then paying attention should suffice to grok the intuition behind the topics. All of the covered topics are accessible as promised with the exception of Euler's formula being a bit hurried and the language used in growth rates being a bit complex.

But I'll never use this once I leave school

Reviewed in the United States on June 12, 2013

Verified Purchase

Have you ever heard someone say, 'I never used math after I left school.'

Of course they didn't use it. They didn't understand it the first time.

But if they'd been taught the way Kalid's explains math, not only would they understand it so well they could use it all the time, but they'd have fun doing it.

Which Pizza will do a better job of feeding my family, the small and medium, or the large? Pathagorean's theorem to the rescue.

Pathagoras? The triangle thing?

Sure enough. But not by memorizing it, by the insight that comparing circles works by the same rules that comparing triangles do.

Ever thought anyone would give you an intuitive sense of calculus? As Kalid says, "We don't need to be writers to appreciate Shakespeare," and we don't need to be math geniuses to appreciate calculus.

There are lots of great courses that will teach you how to do many things, and they are good for what they do. Yet with most of them I got the sense that each lesson only applied to one very specific situation, usually a situation I would never be in. And there were hundreds of these little rules, each applying only to their own very specific situation.

But Math, Better Explained, is totally different. Kalid only talks about a dozen things. One of them is not a rule at all, just a way of looking at things Another one he spent 2 chapters on because the way I was taught it missed how useful it is. Chapter after chapter he demystifies concepts that most of us had given up on. He makes them so clear that now I can apply them in hundreds of situations, situations I'm in, if not every day, at least several times a month, where I want answers, sometimes exact and sometimes just close enough.

If you ever wanted to master math, I haven't found a faster, nor an easier way.

Wilfredo Pareto is famous for a principle called the 80/20 rule. 80% of the value comes from just 20% of your efforts. And the secret to life is figuring out where those 20% efforts are at.

Kalid has done this one better.

If you want 90% of the value of a complete math education for 1% of the effort (but 200% of the fun), this is the book you want to buy.

If you want to clear the fog around key math concepts, and show your family, your children, your friends, how to understand math, this is the book you want to show them.

And if you are just tired of saying, "Oh, I'm not good with math," and instead want to be good at it, this is the book that you want to have fun reading while mastering all those math concepts.

Azad gets my vote for the world’s best math teacher.

Reviewed in the United States on March 11, 2021

Azad is a genius, at least when it comes to teaching. This books is amazing. If I had teachers like Azad, or even just tutors, when I was growing up, I would have loved math. I discovered Azad and this book looking for resources to help my grand daughter with her math. It hasn’t just helped her, however. This book has kindled an interest in math that I never had before. This man deserves some kind of medal from the president. Or at least our thanks.

This truly is an excellent book

Reviewed in the United States on April 11, 2013

I don't have much more to add that hasn't already been said, but I did want add my rating just to give it another 5 star review. Hopefully, the more 5 star reviews the more the book sells and more people will really understand how all this math stuff actually works.

I hate the rigorous approach to mathematics. My learning style requires an intuitive understanding first and then I can learn the rigorous details that help reinforce and sometimes modify my intuitive understanding. There aren't many books that teach math this way, so Kalid's book should be required reading for any author who wants to teach math using an intuitive approach.

The rigorous approach sucks all the enjoyment out of math. It reminds me of when I was in the Army and drill sergeants could somehow suck the fun out of shooting automatic weapons (well, not ALL the fun).

Math without the Mumbo Jumbo

Reviewed in the United States on January 12, 2014

Verified Purchase

Math is always a scary subject for a lot of people but with this book you will be able to see the forest for the trees. The author takes you straight to the point without jargon or strange words for explaining complicated subjects. He breaks down the subject using lay terms and providing examples that you can visualize easily from the book and on your mind. You will not need any special or genius skills to understand the math concepts explained here. His explanations are clear and right on. This book is highly recommended for high school and college math students as well. As soon as you start reading it you will realize this book is a keeper. I consider myself a math freak and still I am learning something new from this book. From this point on you will feel that you dominate Mathematics and not the other way around. Enjoy!

Kalid Azad is a national treasure, and should be given a grant to focus on improving math education nationally. His online content is great, which is exactly what this book puts in print. I thought the book would have some different content.

It does the job for which I bought it. I like the way Kalid thinks.

Reviewed in the United Kingdom on January 16, 2018

Verified Purchase

I purchased this not for my own edification, but to give me ideas on helping grandchildren with their maths. I was looking for new ways to better explain abstract concepts like complex numbers, the base of natural logs etc. Kalid explains a number of things in a way very different to the old fashioned way I learned them 50 years ago. This book served my purpose very well. His treatment of "growth" provides a nice basis understanding for integration and differentiation when calculus appears on the horizon. If you want a new way of explaining maths to young people, I think this does the job. If you are looking for new insights into things you learned by route and never really "felt", you won't be disappointed. If you are looking for a learned maths text, this is probably not what you seek.

I'm happy with it for the purposes for which I purchased it. I'm going to try his book on calculus next, before the grandchildren reach that point. With maths, understanding is everything. It simply cannot be learned beyond a certain level by route. I think this book helps on the understanding.

Enlightening, clear and fun

Reviewed in the United Kingdom on July 27, 2014

I am curious about math concepts. At school I number crunched and rearranged formulae satisfactorily enough to pass exams but never really understood the ideas behind them - such things as 'e' and calculus and why is a circle complete but 'Pi' never ends?
This book is terrific. It does give a real world angle on math concepts and I feel that at least I now have a grasp of the basic ideas- lots of AHAA! moments. It is clearly lifted from a blog,the style is light and conversational. There are a few ' see you next week' type of comments and the content jumps around a bit rather than building logically ( I suppose then it would have to be massive eg Principia). I hope the author will continue with this project - his expositions are great.

Couldn't imagine I'd ever read a mathematics book that had me smiling and finishing a chapter wishing I could read it again for the first time. Seriously. The writing is terrific, the pace gentle and the accompanying graphics clear with excellent and subtle use of colour. Aside from the authors Calculus, I wish there was a second volume to this. Two books are categorically not enough. More please sir.

Great book for a different angle.

Reviewed in the United Kingdom on June 1, 2013

I've been following Kalid's blog for a while and I find it to be a very good source for an alternative look at Maths subjects. I find that when studying a subject (especially a specific sub-part) it's so much more useful to have more than one textbook for a hopefully different stance, well this book gives (normally) quite a unique intuitive view. And usually it's a very useful one, with essential illustration.

To me, it's a distillation of one guy's "A-ha!" moments into a single book, those moments when mathematics seems to beautifully mesh. Not everyone's moments are the same and we may not all agree, but to me at the very least I love to see how other people think about things too.

Also in his blog he replies to comments which is extremely useful too.
