#2Put these on the wall in every classroom. (And make the kids move desks into the hall /s.)

#3Simple to understand. I'm surprised clickbait like this has climbed so high up on HN.

#4How about the prime number problem. It's simple enough to understand.
"A prime number (or a prime) is a natural number greater than 1 that has no positive divisors other than 1 and itself. There are infinitely many primes, as demonstrated by Euclid around 300 BC. There is no known simple formula that separates prime numbers from composite numbers."

Where are you quoting this from? It's ill-defined / ambiguous as you're stating it. I'm a professional number theorist and I don't understand what your question is actually asking. Thanks!

https://en.wikipedia.org/wiki/Prime_number please improve the article :-)

I quoted it from Wikipedia. The problem is the last line. There is no known simple formula to identify prime numbers.
Could you provide more clarification on what's wrong?

What is a "simple formula"? I have no idea what "simple formula" means. In math reseacrch everything must be 100% precise and well defined.

I think they mean something a great deal faster than just dividing by each number to check.

#10I don't really know how to prove something, but for the first problem, it seems like any odd number multiplied by any other odd number (in the example, they choose 3) will always be odd. This can/has been proven. Then, any odd number, negative or positive, with 1 added or subtracted to it, becomes even. Finally, any even number divided by two is still even and approaches two.
"Mathematicians have tried millions of numbers and they've never found a single one that didn't end up at 1 eventually. The thing is, they've never been able to prove that there isn't a special number out there that never leads to 1."
Why are they trying millions of numbers? It seems like those 3 statements are very easy to prove, and explain this "phenomenon." Also, isn't the multiplying by 3 part kind of arbitrary. It seems like the only important part to consider is that if the number is odd, add 1. The multiplying by 3 is unnecessary, and could just as easily be swapped for multiplying by any odd number.
