Hi, I finished calculus 1 in college this past year, and I was reviewing it in the summer to make sure I understand it and have a solid foundation for when continue taking math classes this upcoming year. My math has always been lacking a little from my highschool past where I never paid attention. I remember doing small proofs in geometry in highschool, but that was in my first year, I didn't learn it, and of course I don't remember them now. But that brings me to my question. This past year during calculus we didn't have to prove anything really. We would just be told what something was and then worked examples. However, now when I am going back to look over things I will see a theorem accompanied by a proof. Most of the times these proofs seem a little over my head, and I would never be able to make a proof such as those from scratch. I am wondering whether I should know how to prove things a little bit now, or do they teach you proofs in a higher math class? Also, if I am indeed behind, what is a good way to go about learning proofs, and some good book suggestions? And if I am not behind would it be a good idea to start learning now?
