……逗你乐呵。https://www.amazon.com/dp/B08T8JCVF1 如果你还是想要一本循序渐进的证明入门书，但更喜欢作者用传统教材那种严谨严肃的语气，我推荐 Joel Hamkins 写的《Proof and the Art of Mathematics》。https://www.amazon.com/dp/0262539799
…you entertained. https://www.amazon.com/dp/B08T8JCVF1 If you still want a gentle introduction to proofs but would prefer if the author uses a more serious tone like traditional textbooks, I recommend Proof and the Art of Mathematics by Joel Hamkins. https://www.amazon.com/dp/0262539799
Velleman 的《How to Prove It》极大地提升了我构造集合论证明的能力，让我能更好地啃下 Spivak 的微积分和 Baby Rudin。Hamkins 的《Proof and the Art of Mathematics》则是一本很好的证明写作入门书，集合论的比重没那么大，能更顺理成章地引申到数学分析。OpenStax 的书全都是免费的。
Velleman's How to Prove It greatly helped my ability to construct set theoretic proofs, which better prepared me for Spivak's calculus and Baby Rudin. Hamkins' Proof and the Art of Mathematics is designed as a a good, less set-theory heavy, introduction to proof writing that leads more naturally to analysis. OpenStax books are FREE.
精炼扼要！我刚根据 pg 的推荐[1]开始看 JD Hamkins 写的《Proof and the Art of Mathematics》[0]，“从两种意义上说都是一本绝美的书。不仅写得极美，而且书本身制作也非常精美，多亏了里面大量的插图，这还挺让我惊喜的……
Nice and concise! I just started Proof and the Art of Mathematics by JD Hamkins[0], based on pg's recommendation[1], "is a beautiful book in both senses. It's both beautifully written, but also physically beautiful, thanks to its many illustrations, which I was surprised…
