Why doesn't 1/0 equal 0 but 1*0 does? Is there a reason or is it arbitrary?

Wait. Dividing by zero doesn't equal zero?

Multiplying by zero equals zero.

Dividing by zero is undefined.

1/x tends to infinity as x tends to zero. Strictly seeking, mathematically, one cannot divide by zero, but there are many quantities in physics where this can occur, for instance QFT is plagued with these infinities. There are several techniques to deal with such instances.

I like the sandwich idea. Why would you try to divide a sandwich between zero people and how would you know when you were through?
If there is a god, I want to believe that there is a god.  If there is not a god, I want to believe that there is no god.

I see, but why is it ok to multiply by zero? I'm not being obtuse, I seriously don't know. lol
