20 exact-answer questions with no calculator: surds, indices, exact trigonometric values, algebraic manipulation and fractions.
🧮 Paper 1 non-calculator warm-up — Higher
On Higher, Paper 1 asks for answers in exact form — a surd left as a surd, sin 60° left as √3/2, a fraction left as a fraction — and a rounded decimal scores nothing. This sheet drills exactly that. Twenty questions across simplifying surds and rationalising denominators, the index laws including fractional and negative indices, exact values of sin, cos and tan at the standard angles, expanding and factorising, and arithmetic with fractions and mixed numbers. Give yourself twenty-five minutes and no calculator, and write every answer in its exact form even when a decimal feels more natural. If you find yourself reaching for the calculator out of habit, that is the habit this sheet exists to break.
- 1.Simplify x⁷ × x⁴, giving your answer as a single power of x.
- 2.Rationalise the denominator of 10/(4 − √6), giving your answer in its simplest form.
- 3.Solve x² − 8x + 3 = 0 by completing the square. Give your answers in surd form.
- 4.Simplify 2/(x + 1) + 3/(x − 2), giving your answer as a single fraction.
- 5.Work out 1 1/2 ÷ 3/4 exactly, giving your answer in its simplest form.
- 6.A shape is made by joining a rectangle measuring 10 cm by 6 cm to a semicircle of diameter 6 cm along one of the rectangle's shorter sides. Work out the exact area of the shape, in terms of π.
- 7.Work out the value of .
- 8.Expand and simplify (2x − 1)(x + 5)(x − 2). Write down the coefficient of x in your answer.
- 9.Work out the value of the discriminant b² − 4ac for the equation 2x² + 3x − 2 = 0.
- 10.Simplify (3a²)² × (2a)³
- 11.Expand and simplify (x + 1)(x + 2)(x + 3).
- 12.The decimal 0.272727... repeats the block 27 for ever. Write 0.27 recurring as a fraction in its simplest form.
- 13.Write 7/12 as a decimal, showing clearly which digit is recurring.
- 14.Work out the value of 2⁻⁴
- 15.Factorise fully 12x² + 18x.
- 16.Work out the value of .
- 17.The equation x² − 6x + k = 0 has exactly one solution. Work out the value of k.
- 18.Robert is converting 0.999... (with the 9s recurring forever) into a fraction. He lets x = 0.999... . Multiplying by 10 gives 10x = 9.999... . Subtracting x from 10x gives 9x = 9, so x = 1. Which statement correctly explains this result?
- 19.Write 0.36 as a fraction in its simplest form.
- 20.Expand and simplify (x − 3)²
What is on this worksheet?
The sheet holds 20 questions drawn from the MathsUK bank — the content areas covered: Number, Algebra, Geometry and measures (statements N7, N8, N10, A4, A18, G21). It is pitched at GCSE Higher and takes about 25 minutes to work through in full. It is built for independent practice, with full answers at the end for self-marking.
How to use the sheet well
- Print it or open it on screen — both work. Printing is A4; the screen view fits phones and tablets.
- Do all 20 questions before checking — about 25 minutes is the guide, but there is no time pressure.
- Check the answers — press “Show answers” or print the answer page separately.
- Redo the questions you got wrong — twice as effective as doing 20 fresh ones.
- “New questions” — builds a fresh sheet on the same statements, so you can practise again without repeats.
Why this sheet helps
MathsUK worksheets use questions graded by difficulty and a fair spread of correct-answer positions (the answer is not always (a)) — so the student really has to think about each question rather than guess a pattern. Every question is tagged to a DfE content statement and checked before it enters the bank. The answers come with a step-by-step explanation, not just a value — so a wrong answer becomes a lesson.
