Answer:
Coordinates are based on latitude and longitude lines. They tell us where something is. For example:
45.42083°N 75.69°W is the coordinates for Ottawa, Canada.
The N stands for Northern Hemisphere, just as W stands for Western Hemisphere, E for Eastern and S for Southern Hemisphere. The 45.42083 and 75.69 stand for the lines of latitude and longitude Ottawa stand on. The lines of latitude are always written first. When trying to find coordinates on a map, you must always calculate the lines of latitude first.
