Drills
Evaluating multi-step calculations on a calculator at full accuracy, rounding only at the final answer.
Author note — to cover
- Fluency — keying fraction bars, roots and powers in one go, rounding to 3 significant figures (4 questions).
- Standard form — entering and reading ×10ⁿ values on the calculator display (3 questions).
- Full accuracy — chained calculations using Ans, built so rounding mid-way gives a visibly wrong final answer that the marking rejects (5 questions).
