Answer:
7,065 meters.
Step-by-step explanation:
The problem is asking for "the difference" between two points. "The difference" means you're subtracting. The second point says it is below sea level, though. That makes it a negative number. Thus:
[tex]6960-(-105)=x[/tex]
When subtracting by a negative number, think of it as addition, since the negative cancels out the subtraction sign. This turns it into:
[tex]6960+105=7065[/tex]
There is a 7,065 meter difference between the two points.
