Editing Address (section)

=== {{anchor|cartesian}}Quadrants ===
In cities with Cartesian-coordinate-based addressing systems, the streets that form the north–south and east–west dividing lines constitute the ''x'' and ''y'' axes of a [[Cartesian coordinate plane]] and thus divide the city into '''quadrants.''' The quadrants are typically identified in the street names, although the manner of doing so varies from city to city. For example, in one city, all streets in the northeast quadrant may have "NE" prefixed or suffixed to their street names, while in another, the intersection of ''North'' Calvert Street and ''East'' 27th Street can be only in the northeast quadrant.
