Maps often have a symbol like this to show directions north, south, east, and west. This is called a compass rose because the points on the symbol look like the petals of a flower.
Maps cannot be the same size as the actual area they show because obviously the maps would be too big. Mapmakers, who are called cartographers, create a relationship between the real size and the map size that is shown on a scale. For example, one inch on a map might equal one mile on a road.
Symbols rather than words are often used to shorten and simplify equations. Here are examples of some symbols:
|>||Greater than||10 > 2|
|<||Less than|| 2 < 10|
|>||Greater than or equal to||10 > 10, 9, 8. . .|
|<||Less than or equal to|| 2 < 2, 3, 4. . .|
