Okay, this problem, you have a submarine.
00:02
It starts at negative 1 ,300 meters.
00:05
In other words, 1 ,300 meters below sea level, right? and then it's going to descend, which basically means it's not going up, it's going down.
00:15
So you can think of that as removing a positive or adding a negative.
00:18
I'm going to think of as adding a negative distance.
00:20
And so it's going to go down descending, right? not going to close the surface.
00:24
We're not adding a positive, we're adding a negative.
00:26
It's going down.
00:27
And it's going down an additional 1 ,000 -1 ,000...
