完全同意。我擅自随手拍了一张《实用算术》（Arithmetic for the Practical Man）里的某一页发在下面，给那些深受现代教科书毒害的可怜人看看：http://i.imgur.com/Bg9OiiK.jpg (926KiB)。我看到现代那些动辄超过1000页的可怕巨著，直看得人头晕眼花、不知所措而且……
Completely agree. I've taken the liberty of taking a quick snap of a random page in "Arithmetic for the Practical Man" to include below for those poor people poisoned by modern textbooks: http://i.imgur.com/Bg9OiiK.jpg (926KiB) I see horrible modern behemoths of over a 1000 pages that leave you dazed, confused and…
“实用数学”（Mathematics for the Practical Man）系列虽然年代久远，但绝对值得考虑。据我所知该系列包括以下几本：- 《实用数学》 - 《实用算术》 - 《实用代数》 - 《实用几何》 - 《实用微积分》 -> 最后这本就是理查德·费曼当年自学微积分用的书 (https://physicstoday.scitation.org/do/10.1063/PT.5.9099/full...)……
The “Mathematics for the Practical Man” series, although old, might be a good resource to consider. These are the titles I know are out there: - “Mathematics for the Practical Man” - “Arithmetic for the Practical Man” - “Algebra for the Practical Man” - “Geometry for the Practical Man” - “Calculus for the Practical Man” -> this last one was the one Richard Feynman used to teach himself calculus (https://physicstoday.scitation.org/do/10.1063/PT.5.9099/full...)…
是的。在理查德·P·费曼的《发现的乐趣》（The Pleasure of Finding Things Out）第6页上有一个故事：“当时有一套数学丛书，从《实用算术》开始，然后是《实用代数》，再接着是《实用三角》，我就照着那本书自学了实用三角学。但很快我又忘光了，因为我根本没理解它……
Yes. On page 6 of the book "The Pleasure of Finding Things Out" by Richard P. Feynman is a story: "There was a series of math books, which started Arithmetic for the Practical Man, and then Algebra for the Practical Man, and then Trigonometry for the Practical Man, and I learned trigonometry for the practical man from that. I soon forgot it again because I didn't understand it…
……不懂数学的基础知识。所以我决定从最基础的算术从头学起。像 Spivak 那样的推荐书单你目前大概可以先忽略。我现在在读的书是 J. E. Thompson 写的《实用算术》（Arithmetic for the practical man）和汉斯·马格努斯·恩岑斯贝格尔写的《数魔》（The Number Devil: A Mathematical Adventure），这是一本童书。
…don't know the fundamentals at math. So I decided to start from the beginning with basic arithmetic. You probably should ignore book recomendations like Spivak for now. The books that I use right now are "Arithmetic for the practical man" by "J. E. Thompson" and "The Number Devil: A Mathematical Adventure" by "Hans Magnus Enzensberger" which is a childbook.
