Math, Better Explained (英语) 平装 – 2013年5月3日
Kalid Azad graduated from Princeton University and has been writing professionally for over a decade, from chapters in the best-selling "How to Program" textbooks (from Deitel, Inc.) to technical whitepapers for Microsoft, Corp. Kalid has tutored math since high school (99% percentile for SAT/GRE/GMAT) and is enamored with finding the clearest, most intuitive insights on seemingly-complicated topics. He is the founder of BetterExplained, a teaching website whose explanations are read millions of times every year, including dozens of high school and college courses.

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.
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).
