Nice. thanks. I never understand it. Why, is it hard? I know that divide by zero, it not possible. Because: [I don't have a formal explanation, if anybody have it is nice to reply and give it]. If I have a cake, how can I divide it to 0 people? Or: how to divide x dollar (x>0) to 0 people?

Let's assume division by zero is defined and write 1/0 = x. From that, 1 = 0 * x = 0. Do you see a problem?
