Write as an ordinary number.
Edexcel IGCSE Math A Foundation 1.9.A numbers in standard form
Practise standard-form questions by converting ordinary numbers and performing arithmetic before correcting the coefficient.
How this is tested
- Convert between ordinary numbers and a × 10^n for positive and negative powers.
- Add, multiply or divide standard-form values before correcting the final coefficient.
- Keep the final answer in standard form with coefficient 1 ≤ a < 10 after simplifying.
