Asubmarine is 90 feet below sea level and then moves up 35 feet and then went back down 55 feet. what sea level is the submarine

I believe your submarine would be 110 feet below the sea level.

Hi there!

The sea level is considered as zero (0).

Below sea level is considered as negative.

So :

90 feet below sea level = -90

moves up 35 feet = -90 + 35 = -55

went back down 55 feet = -55 - 55 = -110

Your answer is: The submarine is 110 feet below sea level.

There you go! I really hope this helped, if there's anything just let me know! :)
