A submarine submerged at a depth of -15m, dives 20m more .what is the new depth of the submarine? solution with explain

-15+20=5

-15-20 = ?

-15+20=-35

To find the new depth of the submarine, we need to add the additional depth to the initial depth.

The initial depth of the submarine is -15m (submerged at a depth of -15m), and the submarine dives an additional 20m.

To represent the initial depth mathematically, it can be written as -15m.

Now, to find the new depth, we add the additional depth of 20m to the initial depth:

-15m + 20m = 5m

Therefore, the submarine's new depth is 5m.
