ONT Camp Day 1

Post Number:#1  Unread postby Masum » Sun Aug 23, 2015 9:24 pm

So, this is the first day of online number theory camp. The camp will last 7 days. Every day, there will be some practice problems and discussion on them. You don't have to send me any pm or email for discussion/practice problems. Just comment here. Send me pm just for solutions or if there is some problem or if you have problem misunderstanding some topics.
We will have three/four exams. There will be an exam tomorrow at 9 pm. Practice problems will be posted soon. Stay alert.

Don't worry about that. Correct versions: 1. $a$ divides $\gcd(b,c)$
4. If $30$ divides $a+b+c$, then prove that $30$ divides $a^5+b^5+c^5$
