Substituting into Expressions Examples

What is the resource?

This PDF demonstrates  'substitution' –  swapping numbers for letters in algebraic expressions.  It offers clearly worked examples for secondary learners.

 

Why is substitution important?

Substitution opens up maths problem-solving for all sorts of areas:

  • Formulas: Think science formulas (speed, energy) – you often plug in values
  • Finding unknowns: When we have 'missing numbers' represented by letters.
  • Real-life situations: Prices changes, measurements... substitution finds the final answer.

 

Why is this resource helpful?

The resource makes this skill less mysterious through:

  • Step-by-step guides: Provides a breakdown of how to approach each problem.
  • Varied examples: Covers basic expressions, those with powers, and negative numbers.
  • Increases comfort: Lets students see worked solutions before trying their own.
  • Printable PDF: Handy for independent study or when working through class examples.

This resource acts as a reference tool. Students who master substitution have a powerful maths skill at their fingertips.
