Question

A scuba diver dives 243 feet into the ocean and then swims up 156

feet. What integer represents her final position relative to where
she started?

Answer 1

Her final position would stop at -87.

Explanation:

As she dove 243 feet into the ocean, that means she went down. Therefore she's currently at -243, however she swam up 156 feet ending her up at -87. If that was kinda complicated, then use -243+156 and you'll get -87.
