初めてなのに、優しくしてくださいね・・・

I'm nearly done with the first chapter of Contemporary Abstract Algebra, which is simply a rehash of elementary number theory. I liked this part:

"I was interviewed on the Israeli Radio for five minutes and I said that more than 2000 years ago, Euclid proved that there are infinitely many primes. Immediately the host interrupted me and asked: "Are there still infinitely many primes?"

The rest of group theory is starting to scare me... it's not a matter of difficulty but more of a matter of time - of which I have very little; and I'm starting to encounter many proofs which evade me.
