Theory Practice A
What theory practice a means
In this practice set, you solve short Mathematics questions by using clear steps and basic rules. You practise quick calculations, simple algebra, and geometry so you can answer exam-style questions with confidence.
What you will practise
- Work out profit and loss from buying and selling amounts.
- Expand simple algebraic expressions using the distributive law.
- Find missing angles in triangles using angle facts.
- Choose the correct operation and show brief working.
Before you start
You should already be able to add, subtract, multiply and divide whole numbers. It also helps to know simple algebra symbols and the angle sum in a triangle.

Worked example
One question from this skill's own question bank, shown with its full working.
A trader bought an item for GH₵50 and sold it for GH₵65. Find the profit.
Working: Profit = selling price − cost price = 65 − 50 = GH₵15.
Common mistakes to avoid
- Using the wrong formula for profit or loss, so check whether you subtract cost from selling price.
- Forgetting to multiply every term inside brackets, not just the first term.
- Adding the given angles in a triangle instead of subtracting them from 180 degrees.
- Leaving out working, which makes it harder to spot small calculation errors.
Curriculum and exam alignment
This kind of short-answer practice usually appears in Junior High School Mathematics as learners prepare for exam revision in algebra, commercial maths and geometry. It supports the type of reasoning and calculation often needed in BECE Mathematics papers.
Curriculum notes are a general guide to where this work normally sits. Always check the syllabus your school or examination body is currently using.
