In world Geography I am learning about longitude and latitude. Can you have negative longitude?

Question

We don't say negative in class but, just north and south.

Answer 1

No. Going either east or west from the prime meridian you start measuring in that direction.

Answer 2

You most certainly can have negative longitude. There are two broad ways to show longitude for east-west directions. Either one can use positive number with E and W to show the direction, or one can use positive numbers for east and negative numbers for west. For example, the longitude of New York city is either 71º West or -71º. Similarly, for latitude, one can write N or S after the degrees or use positive or negative numbers, respectively.

Of course, it's also possible to use either decimals or degrees/minutes/seconds, but that doesn't affect the answer that YES you can have negative numbers for longitude and latitude.

Answer 3

No, Because the earth is not flat. So the number cannot be called negative. Even it's flat it still not negative.

There is no such thing.
