Ask HN: Recommend a maths book for a teenager?
During the first year of my undergrad someone introduced me to Gödel, Escher, Bach. I thought it was mind blowing at the time and still find it to be an incredible introduction to formal systems, thinking mathematically and understanding the concept of proofs.<p>All these concepts are central to higher level mathematics, and are not covered in high school (at least not the Danish one).<p>I'm was very thankful for that introduction, hopefully they would be as well :)
