It is undefined or you cannot evaluate it.

Explanation:

You cannot evaluate 80 because there is no real number (call it a) that can be solution of it:

If you try you get:
80=a
rearranging:

8=a0 that is not true!

In Calculus you can have a way out or trick to "visualize" the idea behind 80 by choosing instead of 0 a value that is near 0 but not 0, such as 0.001
If you try to get as near as possible to zero increasing the number of zeros after the point you'll get very big numbers.
80.1=80
80.01=800
80.001=8000
etc.
the idea is that when you try to get near zero the result of the division gets bigger and bigger....or infinite!
