| 6) Nope 7) True but I was looking for something a little less obvious 8) It is Skewes Number, you'll get credit for that--but it doesn't require arrow notation 9) N doesn't represent the Null Set 10) Nope 12) Correct 13) No. The numbers that are named after this woman has a prime quality to them. --- Current Point Totals: Heian-794 - 6 --- The list of questions (answered or unanswered) can be found in the first post of this thread.

| 6: the definition of a prime number is that its factors include numbers besides itself, and 1. Itself being 1, it can't be prime. | |||

| What's wrong with my answer? I just looked it up real quick: prime number A number that has exactly two factors, 1 and the number itself (cf Venn Diagrams Discussion). and... A prime number is a positive integer that has exactly two positive integer factors |

NSNick: alright--i guess i'll have to accept it since i wasn't specific enough  (well, this is the first time i've moderated such a thread so i apologize for my inexperience)Why I rejected it in the first place because that is a weak reason why I believe -- plus, that isn't the one I had in mind. So, #6 is still up for grabs, but this time reworded to be: "Give a strong reason why 1 can't be a prime number." --- Current point totals Heian-794 - 6 points NSNick - 1 point |

| I think Nick's answer to #6 is perfectly fine -- BTW, when I took the SAT there was a question about whether or not 1 was prime, and, thinking that it was, I got it wrong! Not so sure how much this has to do with sets, but I'm going to have to say "infinity", (or "aleph" if you're a Cantor fan) for #9. |

| well, i dunno...i was looking for a stronger reason but I guess i can't expect that much out of people... anyways, yeah, Heian-794, you are right. --- Current point totals Heian-794 - 7 points NSNick - 1 point --- current questions can be found in the first post |

| The answer to #13 just jumped into my head! Sophie Germain and her prime numbers are of course what you're looking for! | |||

| I just noticed that #11 hasn't been answered. The largest known twin primes are: 665551035 x 280025 +/- 1 |

| #7 nope, it is prime, but what makes this prime number fairly unique from the others #11 yup --- Current point totals Heian-794 - 9 points NSNick - 1 point --- current questions can be found in the first post |
