Hey there!
The correct answer would be~
The diver is now swimming at -7 meters.
Here's how:
If the diver is already swimming at negative 10, going deeper would add to that.
(-10) + (-3) = -13
So at this point, he is at -13 meters. However, it says he rises 6 meters.
So if he rises, we need to subtract.
13 - 6 = 7
Therefore he is now at -7 meters.
Hope this helps!
