1. Arianna runs up 4.5 flights of stairs.
How far will Arianna have to run down
to represent an additive inverse?

The additive inverse of a number is the number that, when added to the original, gives a sum of zero. In this case, Arianna runs up 4.5 flights of stairs, so the additive inverse would be running down the same number of flights.

To represent an additive inverse, Arianna would have to run **down 4.5 flights of stairs**. This is because:

\[ 4.5 + (-4.5) = 0 \]

Here are five related questions to expand this concept:

1. What is the additive inverse of -7?
2. How do you calculate the additive inverse of a fraction?
3. If Arianna runs up 3 flights and then down 2 flights, what is her net displacement?
4. What does the term "inverse" mean in mathematical operations?
5. How would you graph Arianna’s position if you represent her movement using a number line?

**Tip:** The additive inverse of any number \(x\) is simply \( -x \).
