Explanation:

When evaluating a complex fraction or root on a scientific calculator, press the fraction button (□□) first so the display matches the printed question, or put brackets around the entire numerator and denominator: (top) ÷ (bottom).

In GCSE exams, always write down the full calculator display (or at least the first 6 digits) as your first line of working before rounding to the requested number of decimal places or significant figures.

Example 1: Use your calculator to work out 14.8 + 7.65.2 − 1.72.
Give your answer to 2 decimal places.

Solution:

• Numerator: 14.8 + 7.6 = 22.4
• Denominator: 5.2 − 2.89 = 2.31
• Full display: 22.4 ÷ 2.31 = 9.6969696…
• Round to 2 d.p. → Answer: 9.70

Example 2: Work out √(8.52 + 4.23)3.1 correct to 3 significant figures.

Solution:

• Inside square root: 72.25 + 74.088 = 146.338
• Numerator: √146.338 = 12.097024…
• Full display: 12.097024… ÷ 3.1 = 3.9022659…
• Round to 3 s.f. → Answer: 3.90
