At that age, I enjoyed Number Theory by George E. Andrews https://www.amazon.com/Number-Theory-Dover-Books-Mathematics...
on “Ask HN: Recommend a maths book for a teenager?” ↗Very cool. I'd also recommend Number Theory by Andrews. It's a great comprehensive introduction.
on “Number theory explained from first principles” ↗…working through these really solidified my grasp on the basics. 2. George Polya. How to Solve it. A short book giving excellent high level advice on mathematical problem solving. 3. George E. Andrews, Number Theory. I worked through this freshman year contemporaneously with my first proof based class on simple logic and set theory. A very beautiful and accessible introduction to basic number theory. The combinatorial/geometric…
on “Ask HN: Math books that made you significantly better at math?” ↗…Snapshots Polya, Mathematics and Plausible Reasoning Pappas, The Joy of Mathematics Gardner, The Colossal Book of Short Puzzles and Problems Winkler, Mathematical Puzzles: A Connoisseur's Collection Andrews, Number Theory (Dover Books on Advanced Mathematics) - The last book is not really that advanced, It can be understood by most with an understanding through high school algebra II.
on “Ask HN: Good books on mathematics for somebody who's only taken high school math?” ↗…glossy print), and more focused on proofs and algorithms. You can see them here http://store.doverpublications.com/by-subject-mathematics.ht.... I particularly liked Probability: A concise course, and Number Theory by George Andrews. Amazon used to have a great number of graduate preparation book lists which always included books such as Rudin's Principles of Mathematics Analysis, and Halmos' Finite Dimensional…
