The number for sea level would be 0. Everything above it is a higher number and everything lower is a negative number.
Depends upon where you are at the moment. Most of the nation is above sea level (positive numbers) Death Valley (CA) is 250 feet below sea level (negative number)

40 feet below sea level is at a higher elevation than 14 feet below sea level. Elevation is measured by the distance above or below a reference point, such as sea level, so the higher the number below sea level, the lower the elevation.
Mount Kilimanjaro 5895 meters above sea level
The integer that represents 850 feet below sea level is -850. In the context of elevation, sea level is considered 0 feet, so any depth below sea level is expressed as a negative number. Therefore, 850 feet below sea level is indicated by -850.
14.7 psi at sea level
The coastal plain region of the US ranges in elevation from sea level to around 200 feet above sea level. On average, the elevation of the coastal plain region is approximately 50 feet above sea level.
The number 0 on a topographic map usually represents the contour line for sea level, also known as mean sea level. This line shows where the elevation of the land is equal to the water level of the ocean.
Any number of cities are on the coast, and thus at least partially at sea level. If you allow cities below sea level to be included, then Jericho on the shore of the Dead Sea is certainly a good candidate.
Yes, that is correct. Altitude above sea level, for example, is negative or positive - if you are below sea level, a negative number will be used.
It is because you are going "below" sea level. It is like saying going below zero, since sea level is at zero elevation. If you were to go "below" zero, you would get a negative number, the same with going below sea level. Since you are going below 0 [elevation], you write your elevation below sea level in a negative value.
Arizona's highest elevation point is Humphrey's Peak and is 12,637 feet (3,852 meters) above sea level
