## Undefined or zero integral

Hi
I would like to know what is ∫1/x^2-∫1/x^2 from 0 to 2.is it zero or undefined meaning that it is infinity ? (because each integral is undefined at zero).

Every element of that substraction is a divergent improper integral and, thus, the whole operation is undefined.
