Bounds - Error Intervals Explained

Master Bounds and Error Intervals in this clear and easy-to-follow math tutorial. Stop getting confused by upper bound and lower bound calculations! This video is perfect for students revising for IGCSE Mathematics (0580), Edexcel IGCSE Mathematics A and Mathematics B, GCSE Mathematics (Edexcel, AQA, OCR), or anyone who needs to understand limits of accuracy. In this lesson, we will cover everything you need to know about error intervals, including: *** What is an error interval? *** How to find the lower bound (LB) and upper bound (UB) of a number rounded to the nearest 10, 100, or whole unit. *** How to calculate bounds for numbers rounded to decimal places. *** How to find the error interval for values rounded to significant figures. *** How to correctly write the final error interval using inequality notation. *** Worked examples of typical exam-style questions. This video will help you build confidence and secure full marks on bounds questions in your exams. 🔔 Stay Connected!
