How do net exports, when calculating GDP, impact the overall economic output, considering they are both added to and subtracted from GDP?

Net exports, which are the difference between a country's exports and imports, play a significant role in calculating GDP. When net exports are positive, meaning exports exceed imports, they add to GDP and contribute to economic growth. Conversely, when net exports are negative, meaning imports exceed exports, they subtract from GDP and can hinder economic output. Overall, net exports impact the balance of trade and influence a country's economic performance within the global market.
