End of video remarks

Description

This video is an introduction to Index Notation and explains all the key terms and concepts which will be covered in later videos. I use lots of worked examples to ensure a complete understanding of the index notation including the base and index of a number. I look at how Barry tries to confuse us by using other words to describe indices such as Powers, Exponents and my own favourite - floaty numbers. Using a mix of humour and explanation I hope to ensure that the Mathematics taught in this topic is entertaining and helpful for all levels of students.
