Exchange between countries: barter and money, the bases of trade, balance of trade, bilateral and multilateral trade, dumping, the WTO, trade blocs and types of ports.
| Balance of trade | exports − imports (positive: favourable; negative: unfavourable) |
| How much cheaper (dumping) | home price − price abroad; as % = difference ÷ home price × 100 |
| Price with a tariff | price × (100 + tariff %) ÷ 100 |
| Barter chains | pots per basket × baskets per sack = pots per sack |
| Trade blocs | generate about 52% of world trade |
| Port examples | packet stations Dover and Calais; entrepot Singapore; out port Piraeus for Athens |
