Certainly!
To represent a location that is below sea level, we use a negative sign. This is because below sea level is considered to be in the negative direction relative to the zero level, which is sea level itself.
For a position that is 100 meters below sea level, we denote this with a negative value. Therefore, we write:
100 meters below sea level as [tex]\(-100\)[/tex] meters.
Thus, the appropriate representation is:
[tex]\[ \boxed{-100} \][/tex]
This indicates that the position is 100 meters below the sea level.
