Because either way it would still be the same. There is only a maximum of 180 degrees longitude. If you move 180 degrees east and 180 degrees west, you will still end up at the same place, so there is no need to designate east or west for it.
Because 0 degrees longitude is the Prime Meridian. The Prime Meridian is a line that goes around the entire globe on longitude 0. [The Prime Meridian is the exact same thing as the Equator, just going up and down instead of left and right.]
0 longitude is not designated East or West for the same reason that the number 0 is not negative nor positive. The 0 meridian It is reference point for defining East or West.
180 longitude is exactly the opposite side of the earth from the Greenwich meridian. It is as far East as it is West so it would not be appropriate to label it as either.
It is the Prime Meridian. It's Like how the Equator is not North or South
The degree of longitude east of 5 degrees west is 4 degrees west longitude.
East or west longitude?
Lima, the capital city of Peru, is located at 77 degrees West longitude.
Subtract the east longitude from 360, and you'll have the west longitude.
Longitude is the angular measurement in degrees east or west of the Prime Meridian. The Prime Meridian is at zero degrees; going east, your longitude is in degrees and minutes east, while going west your longitude is measured in degrees and minutes west. A circle is 360 degrees, so the maximum longitude is 180 degrees either way. At the 180 degree line (called the "anti-meridian") the measurement is neither east nor west.
The degree of longitude east of 5 degrees west is 4 degrees west longitude.
Because it's both. 180° east longitude and 180° west longitude are both the same line, exactly halfway around the world from the Prime Meridian.
Jamaica is entirely east of 80 degrees west longitude. The farthest west point on the island, southwest of Negril, is at about 78.4 degrees west.

East or west longitude?
Venezuela is a large country whose boundary, east to west, ranges from about 60 degrees west longitude to about 73 degrees west longitude.
Lima, the capital city of Peru, is located at 77 degrees West longitude.
Subtract the east longitude from 360, and you'll have the west longitude.
121 degrees east longitude
Longitude is measured in degrees east or west.
Longitude is the angular measurement in degrees east or west of the Prime Meridian. The Prime Meridian is at zero degrees; going east, your longitude is in degrees and minutes east, while going west your longitude is measured in degrees and minutes west. A circle is 360 degrees, so the maximum longitude is 180 degrees either way. At the 180 degree line (called the "anti-meridian") the measurement is neither east nor west.
