[00:00:00]Y plus M equals C plus G plus I plus X.

[00:00:04]Subtract M from both sides. You get Y equals C plus G plus I plus X minus M.

[00:00:10]The expenditure form of GDP. Now look at the trade part. X minus M, net exports, the trade balance. If X exceeds M, the country exports more than it imports, trade surplus. If M exceeds X, the country imports more than it exports, trade deficit. Quick example. Exports of 600, imports of 250. The trade balance is 350, trade surplus. Flip the numbers.

[00:00:39]Imports of 600, exports of 250. Trade deficit of 350. Same arithmetic, opposite sign. Both situations arise from the same accounting identity.
