Answer:
Jane is not correct.
Step-by-step explanation:
Jane must have complete several examples using positive numbers. That conclusion does not apply for negative numbers.
Let's see an example:
Given the number 5:

- the opposite of this opposite number: is 5
Note that is the same number and it is positive.
However, if we check the same situation with a negative number:
