When reading grid coordinates on a map, which directions should you read?

• A. Right and Up
• B. Left and Down
• C. Up and Right
• D. Right and Down

Answer: (A)

Reading grid coordinates uses two axes: horizontal (east-west) and vertical (north-south). The horizontal value, called the easting, increases as you move to the right, while the vertical value, the northing, increases as you move upward. So you interpret a grid reference by first moving to the right (east) to reach the correct column, then moving up (north) to reach the correct row. That is why Right and Up is the correct sequence. In practice, this matches how grid references are structured: easting first, northing second. Moving in the other directions would not align with how the coordinates are defined, since you’d be changing the wrong axis or moving toward decreasing values.
