False; the scenario is not possible.

Step-by-step explanation:

This scenario is not possible. I will demonstrate it by representing a number by . There are two possibilities: and . Let's try both:

The sum for positive and its absolute value is not negative. Let's try with the negative value of now:

The sum for negative and its absolute value is not negative either, it is zero which is neither negative or positive. Therefor, we can safely say that the scenario described is not possible.

Not if you keep the ' l ' before the ' XX ' where it belongs. If it's before, then it means take the ' l ' away from them, and you get 19 just as you should. Now I understand this crazy question that keeps coming around.
