ELI5: How do some math problems become so massive they take up full massive chalk boards?
gpt
Some math problems are so massive, they involve more than just a chalk board, but rather entire books with hundreds, even thousands of pages. Most of it is establishing the problem in a formal, concrete way, and then creating a mathematical framework which you can use to solve the problem.

For example, suppose your problem is trying to determine the number of prime numbers in the range 1 to 100. Well, first you have to define what a prime number is. Now you have to show some way to find prime numbers. Now you have to actually calculate the solution. Even for something trivial like this, we could probably fill a chalk board.
