How do you use numbers and directions to describe the locations on a map?

To describe locations on a map using numbers and directions, you often reference a grid system, where the map is divided into sections identified by coordinates. These coordinates typically consist of latitude and longitude values, which pinpoint specific locations. Additionally, directional indicators such as north, south, east, and west help clarify the relative position of one location to another. For example, you might say a location is "30° N, 90° W," which specifies its exact coordinates, or describe it as "two blocks east and one block north of the park."
