Question

Can someone please help me with this ? What is the change in elevation from 134 feet below sea level to 29 feet above sea level? possible choice are ; , -163 , 163 , -105 ,or 105 ,

Answer 1

If you move from -134 feet to + 29 feet you have actually moved a distance of 134+29 feet = 163 feet.
In this case all the signs tell you are your position relative to sea level.

Answer 2

If you had to walk up stairs from the 134th parking level underground
up to the 29th floor, how many total floors would you have to climb ?

-- How many from 134 below ground up to the ground ?

-- Then how many more from the ground up to the 29th floor ?

-- How many is that all together ?
