That doesn't explain it, the correct explanation is now create piles of zero books, how many piles would you need?

With the right teacher, anyone can be taught.

Or you can just burn the books or something and then 10/0=0

You would need 0 piles.

Unfortunately, I have yet to meet the teacher who can teach me maths. I think I have numeric dyslexia or something. As soon as I try to understand even high school level maths, my brain starts to hurt. :/

You would probably just need to look at it in a different way. Also, I find that if you really try with something you'll eventually lose yourself in what you're doing and you'll definitely make progress.

Nope, if you burn the books you have 0 books, not 10. You can't divide 10 books into 0 piles; it's just impossible.

That's not correct. The number of books in the pile is the outcome of the division, not the number we're dividing by. As in 5 piles of 2 books each is 10/5=2. The number of piles is what we're dividing by, so the question of 10/0 is the question of dividing 10 books into 0 piles. Physically impossible.

You don't divide them at all so it should be zero.

I'm just trying to apply common sense, I already know I'm wrong.

To consume the 10 books...
