Upper and Lower Bounds with exam question examples

In this video, we will cover the basics of upper and lower bounds, and how to apply them to solve problems in Maths exams.

We will start by defining what upper and lower bounds are, and how they differ from exact values. Then, we will walk you through some examples of how to find upper and lower bounds in different scenarios, including rounding to a given number of decimal places, estimating the range of possible values, and using interval notation.

By the end of this video, you will have a solid understanding of how to use upper and lower bounds to make reasonable estimates and approximations in your IGCSE maths exams, which can help you avoid making costly errors and earn more points on your tests.

So if you're an IGCSE maths student looking to improve your skills in upper and lower bounds, or if you simply want to brush up on this important concept, then this video is perfect for you! Watch now and start mastering upper and lower bounds today.
