Is infinity minus infinity zero?

It is impossible for infinity subtracted from infinity to be equal to one and zero. Using this type of math, it would be easier to get infinity minus infinity to equal any real number. Therefore, infinity subtracted from infinity is undefined.

What happens if the numerator is 0 in limits?

Typically, zero in the denominator means it’s undefined. However, that will only be true if the numerator isn’t also zero.
