How come people say you can't divide by 0?

That's true in most normal contexts, where you'd expect there to be real numbers. But actually, it's allowed for variables in a computer program to be set to 0. I think you're referring to dividing by 0 in a code, when you have a variable assigned to 0, like in the number "4/0" or the formula "2+2/0". In a code, the computer never tries to actually do this; instead, it just shows an error message saying that it's impossible to calculate the answer.

I don't know why that is. Can you tell me more?
