Bounds and error intervals exam questions for GCSE maths, with worked solutions
Practise bounds with exam questions written the way GCSE papers test them: writing the error interval for a number that has been rounded or truncated, finding the least and greatest values a measurement could be, and working out the upper or lower bound of a calculation such as a speed, an area or a total. Every question comes with a worked solution and an answer, and Remix gives you a fresh version with new numbers whenever you want another go.
71 questions: 44 Higher, 11 Foundation and 16 for both tiers. Every question has a worked solution and an answer. Type your answers in and the page marks them as you go.
