Problem: A submarine is at a depth of -120 feet below sea level. If it rises 40 feet, what will be its new position?

Solution:

1. Understanding the Problem:

- The submarine is currently at a depth of -120 feet.
- It rises 40 feet.
- We need to find its new position.

2. Choosing the Operation:

- To find the submarine's new position, we need to add 40 to -120.
- -120 + 40 = -80
- The submarine's new position is -80 feet below sea level.

3. Checking the Solution:

- We can check our answer by substituting -80 for the submarine's new position in the original problem.
- -80 is 40 feet higher than -120, which makes sense.
- Our calculations are correct.

Therefore, the submarine's new position is -80 feet below sea level.
