How WAEC marks this
Examiners award method marks (M1) for stating the formula/definition and accuracy marks (A1) ONLY when SI units are written.
Watch out for
Writing bare numbers without working or omitting SI units loses up to 50% of Paper 2 marks even when the final value is right.
Lesson content
Overview — Trade, Commerce and Industry: Definitions and Relationships
Distinguishing trade, commerce and industry and how they connect. This lesson is at the beginner level — by the end, you'll be able to recognise this question type, apply a reliable method, and avoid the traps that cost marks.
Key Concept
Industry is the production of goods (extractive, manufacturing, or constructive); trade is the buying and selling of those goods; and commerce is the broader term covering trade plus the 'aids to trade' (banking, insurance, transport, communication, warehousing, advertising) that make trade possible.
Why It's Tested This Way
WAEC/JAMB test these definitions precisely because Commerce as a subject is built around this hierarchy — industry produces, trade distributes, and commerce is the umbrella system connecting production to the final consumer.
Method
When answering, be ready to state each term's definition separately and then explain the relationship: commerce is the widest term, containing trade, which in turn depends on industry for the goods it exchanges.
Worked Example
Worked example: A textile factory (industry) produces cloth; a trader buying that cloth to sell to consumers is engaged in trade; and the bank financing the trader's purchase, the lorry transporting the cloth, and the insurance covering it in transit are all aids to trade — together with the trade itself, they make up commerce.
Second Worked Example
Second worked example: If poor road transportation (an aid to trade) prevents farm produce from reaching urban markets, trade in that produce is disrupted even though the industry (farming) itself is unaffected — illustrating why commerce depends on more than production and exchange alone.
Common Traps
Common trap: using 'trade' and 'commerce' interchangeably — WAEC specifically tests that commerce is the broader concept, encompassing trade and its aids, not merely a synonym for buying and selling.
