Longitude is either 'East' or 'West' of the [Greenwich] meridian. Adding letters to a number makes calculations with it difficult, along with being awkward to store in computers, so using the normal number line with negative numbers to the left:
makes the calculations and storage easy.
For example, Land's End at 5o44'W becomes -5o44'
and Great Yarmouth at 1o44'E becomes 1o44'
Negative latitude is latitude south of the equator. Negative longitude is longitude west of the Prime Meridian.
That's OK, it's not a problem. West longitude is commonly written as a negative number.It's much easier for computers to store and manipulate coordinates in that form.For the same reason, you'll occasionally see south latitude written as a negative number.
Negative longitude meabs that the ballon is in the western hemisphere.
As you know, the latitude number must be further clarified as 'north' or 'south' latitude, and the longitude number must be further clarified as 'east' or 'west' longitude. But when you do that, it's hard for a computer to read the information ... which has become a pretty important consideration now. So nowadays, it's common to see latitude written as ' + ' for north and ' - ' for south, and longitude written as ' + ' for east and ' - ' for west. Computers understand the difference between positive and negative numbers very well, and this makes it easier all around.
The difference in longitude between two places is:Absolute value of [ (one longitude) minus (the other longitude) ].The easist way to calculate it is as follows:--> If both points are in the same hemisphere(both east longitude or both west longitude):-- Subtract the smaller number from the larger number.--> If the points are in different hemispheres(one east longitude and one west longitude):-- Add the two numbers.-- Subtract the result from 360.

Negative latitude indicates latitude south of the equator, or the southern hemisphere. Negative longitude indicates longitude west of Greenwich, or the western hemisphere.
The negative of a negative number is a positive number.
A negative number divided by a negative number is a positive number.
A negative plus a negative still gives a negative answer.
negative number subtracted FROM a negative number will be negative
The answer to a problem that has a negative number added to a negative number would be negative.It would be a negative
A positive number. Positive Number x Positive Number = Positive Number Positive Number x Negative Number = Negative Number Negative Number x Negative Number = Positive Number
negative.
A negative number. A positive number x a positive number = a positive number A negative number x a negative number = a positive number A positive number x a negative number = a negative Hope this helps :D
