Answer:

-800 + 250 = -550

-550 - 86 = -636

The sub is 636 feet below sea level.

Explanation:

u start off with -800 since its 800 feet below sea level then you add 250 since it ascends 250 feet which gives you -550 then you subtract 86 since it descends that many feet. when you do all of that you get -636 which in wording would be 636 feet below sea level

Answer:

636 feet below sea level

Explanation:

Below sea level is the same as a negative number.

-800 + 250 = -550

-550 + -86 = -636 (This equation is the same as -550 - 86)
