What objectives set e means

You practise short Core Maths objective questions that test speed and accuracy. The set helps you work with powers, algebra, and percentage calculations, which are common in timed tests.

What you will practise

  • Multiply numbers with the same base using index laws.
  • Divide algebraic terms by subtracting the powers.
  • Find percentages of money and other simple quantities.
  • Choose the correct answer quickly from four options.

Before you start

You should already be comfortable with basic multiplication, division, and simple fractions. You should also know how to read powers and percentages.

Worked example

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

Question

Evaluate 2³ × 2².

  • 32
  • 16
  • 64
  • 8
Answer: 32

Working: 2³ × 2² = 2^(3+2) = 2⁵ = 32.

Common mistakes to avoid

  • Adding powers when multiplying is wrong; keep the base and add the indices.
  • Dividing powers by multiplying the indices leads to wrong answers; subtract them instead.
  • Forgetting to turn a percentage into a fraction of 100 gives an incorrect value.
  • Dropping the currency sign or units can make a correct calculation look incomplete.
