Which book should I read first?

I have two books, both on subjects I'm fascinated by, both subjects way over my head.

The first is the four color theorem,  the second on Abel's proof that the quintic is unsolvable.

Which would be more approachable for someone who's education only includes High school up to and including Calculus? Which is more interesting to you guys? Which am I going to get halfway through, realize it's much harder than thought and give up in a fit of rage?

Four color theorem ... an interesting aspect is involving computer programs in a proof.

Well, Abel's proof is a bit out-of-the-way and abstract. The four color theorem has lots of applications and is a good exercise using counting arguments. It's totally up to you, of course, but I'd probably go for the four color theorem.

When you say "out-of-the-way" What do you mean?

Well, from what I've heard, it uses group theory, which is some pretty complicated abstract maths, and it likely doesn't have many applications. After all, it's just a proof.

That makes more sense, thanks.

Re: Which book should I read first?

It probably uses some form of Galois theory, which builds off of group theory.  I remember trying to learn Galois theory after an introduction to group theory, but I couldn't even get the least bit into it.  I would certainly recommend something else, for the time being.  But Galois theory has been called one of the most beautiful of all the mathematics, so it's certainly something to come back to when you're ready.

However, the four color theorem isn't every simple either.  You say you have only had up to high school calculus, then I wouldn't imagine you would have a lot (or any, really) combinatorics.

One book I would recommend is the construction of the number systems.  From Numbers To Analysis, by Rana is a book I have.  The construction of the integers from the naturals and rationals from the integers would be something quite doable for anyone who has a good understanding of algebra.  The construction of the reals and natural numbers on the other hand might be a bit much.

However I do recommend trying to bite off more than you can chew.  Just remember not to get frustrated when doing so.

Re: Which book should I read first?

By now I have tried reading about 5 different books about number theory, and although I've done some exercises, everything I've learnt seems to slowly be slipping away. After all, I'm not going to encounter number theory again until university, and that's still 2 years away.
