How do imports and exports affect the Gross Domestic Product (GDP) calculation?

GDP Formula

GDP=C+I+G+(X−M)\text{GDP} = C + I + G + (X - M)GDP=C+I+G+(X−M)

Where:

CCC: Consumption

III: Investment

GGG: Government spending

XXX: Exports

MMM: Imports

Why Imports Are Subtracted and Exports Are Added

Exports represent goods produced domestically and sold abroad, contributing to domestic production (added to GDP).

Imports are goods produced abroad and consumed domestically, reducing domestic production (subtracted from GDP).

Why the Answer is C

The formula directly supports adding exports and subtracting imports.
