What theory practice a means

You practise short Core Maths questions that test algebra, factorising and rearranging formulae. This helps you work faster and more accurately in paper-based WASSCE practice.

What you will practise

  • Make a chosen letter the subject of a formula.
  • Factorise simple expressions using common algebraic patterns.
  • Solve linear equations with brackets and numbers.
  • Check your final answer against the original expression.
  • Write clear working steps for short-answer theory questions.

Before you start

You should be comfortable with basic algebra, including brackets, simple equations and expanding expressions. You also need to know how to substitute values and handle multiplication and division of terms.

Worked example

One question from this skill's own question bank, shown with its full working.

Question

Make r the subject of the formula C = 2πr.

Answer: r = C/(2π)

Working: Divide both sides by 2π: r = C/(2π).

Common mistakes to avoid

  • Changing only one side of the equation when rearranging. Do the same operation on both sides.
  • Forgetting the pair form in a difference of two squares. Look for x² − a² and write two brackets.
  • Dropping a negative sign when moving terms across the equals sign. Check signs carefully at every step.
  • Stopping after a partial factorisation. Always see whether the expression can be simplified further.

Curriculum and exam alignment

Ghana GES SHS syllabusWASSCE

This type of work usually appears in SHS algebra topics and is often revised across SHS 1 to SHS 3 before exam practice. It supports the style of short, written responses you may meet in WASSCE 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.
