Dividing by zero

[ITChick]

I'll try to explain it with salami sandwiches (simply because I am eating one now)

Let's say that I have four sandwiches and I want to share it between four people. (4/4). Easy. Each person gets one.

If I want to share it between two people (4/2), each person gets 2.

With one person, the lucky (maybe fat) person gets 4 (4/1)

Now I want to share it between 0 people. Uhm. Can't be done. The poor sandwiches will sit there uneaten forever. If I ask you how many sandwiches each person got, you will probably reply "which people!? There are no people!"

It gets even worse if I ask you: ok, how many sandwiches would each of these 0 people have to eat to ensure there are no more sandwiches left. You can't say 0, because then I still have the 4 stupid sandwiches.

This is different from multiplication. Let's say that I can make 10 sandwiches from one load of bread.

If I have two loaves I can make 20 sandwiches. (2x10)

If I have one loaf I can make 10 (1x10)

If I do not have any bread, I just can't make any sandwiches (1x0)
