一些有趣的事我找到在生活中
好了,这次不是悬疑故事,没有破窗而入的狗头生物,没有追踪杀人的唐氏综合征患者,这一切仅仅是阿列克谢身边发生的事。除此之外,我会谈论一些事情和朋友们,如果这是不适合的对于我去把这些发言放在主区。

Yes, in number theory you need to do a lot of logical reasoning, and you showed yourself excellent in this. But here is one thing, like, you can do the multiplying for many times, for example, 2x2x3, 2x5x5x11, 11x17x17x19x19x23...... not just combinations of two given numbers, like 2x2, 2x3, 5x7, so even if the prime numbers are finitely countable, we can still construct infinite numbers based on that.
Amazing, then I will show you the way to prove this, also mainly logical reasoning, not much calculation.
First of all, we can list all the prime numbers and there're only finite ones of them, let's call them A, B, C, D, E, F, G (start singing alphabet song)......So every natural number that exists will be fully divided by at least one of them, do you agree?
now let's find a Russian letter Д=ABCDEFG...+1, here is A times B times C times...just all of them timed together and then plus one.
So let's randomly consider a number, E for example, ABCDEFG... will be fully divided by it, because ABCDEFG...=ABCDFG... x E, but for the number Д, we have 1 remaining after being divided by E, so number Д won't be able to be fully divided by E.
If you consider any other prime numbers in the list, all will be the same, so Д can't be divided fully by any given prime numbers, so it's a new prime number itself, contradicting to our list of alphabet song.
