If Laura ascends 8 feet, her new position relative to the surface is 24 feet below the surface.
How to assign sign to the like and unlike algebraic expression coefficients?
If the direction is same (like coefficients), we add them and if the direction is opposite (unlike coefficients) then we subtract them. The sign can be taken as per our convenience for a particular direction.
Similarly, as given, if Laura is 32 feet below the surface in a cave (say negative direction)
- 32 feet
and then further she ascends 8 feet that is upward direction (say positive direction),
+ 8 feet
then for calculating final distance of Laura position from surface, we get the expression as:
-32 + 8 = - 24
Hence the final result value is negative 24, it means Laura is bellow the surface, by the distance of 24 feet.
