Question

A scuba diver is swimming around a coral reef 12.25 meters below sea level. He ascends (swims upward) 8.5 meters to look at a sea turtle. Write an expression to describe the situation.

Answer 1

-12.25+8.5

Answer 2

Yes, if the diver is going down, that means you are heading towards the negative, so the scuba diver is 12.25 m below sea level (-12.25) and if he swims up 8.5 metters, you would have to add 8.5, so therefore you would end up with -12.25 + 8.5

Answer 3

I should have explained it sorry :\
