You cannot divide by 0 so therefore you would get an error if typed on to calculator for example.

Well, you can divide by zero, but that is the same as not dividing, at all. And, yes, dividing by zero with computer/calculator gear will usually produce an error.

For instance, 11 divided by zero equals 11.

Negative 17 divided by zero equals negative 17.

I'm sorry, the above is absolutely wrong, negative 17 divided by zero is not negative 17, it is undefined. A simple proof of this is as follows:

-17/x = -17

multiplying both sides by x we get

-17 = -17x

then dividing both sides by -17, we get

1 = x

Obviously 1 is not equal to 0, so -17/0 cannot be equal to -17.

We can use something similar to answer the original question of what -2 divided by 0 is:

-2/0 = x

if we multiply both sides by 0, we get

-2 = 0x

therefore x must be something which, when multiplied by 0, results in -2.

Such a number does not exist, and therefore numbers with a denominator of zero are undefined.
