The concept of infinity over negative infinity is a mathematical paradox that can be difficult to understand. In mathematics, there is no such thing as infinity over negative infinity. This may seem counterintuitive because when you divide something by zero it should equal infinity, however this does not apply in this case. The reason for this is that dividing by zero or any other number involving a variable with an undefined value will yield an indeterminate form which has no definite answer and cannot be simplified further.
In terms of the concept of “infinity over negative infinity”, we have to consider what happens when two infinities are combined. Generally speaking, adding or subtracting infinities results in one new infinite value; however, when multiplying or dividing two infinites together (or just one positive and one negative) the result remains indeterminate as mentioned before. Therefore, while it might appear possible to calculate “infinity over negative infinity” at first glance it simply cannot be done because any resulting calculations would yield an indeterminate form with no definite answer.
