Don't you just love the idea of taking something really big and making is smaller ... errmmm ... not unless it is Mathematical. So, here is a video aimed at those in and around Year 10 age who are looking at learning more about Logarithms. This is the first video in a short series in which I explain what a logarithm is, why we need it and how to convert from "raw" numbers into logarithmic numbers and vice versa. There are lots of worked examples and I explain it in a way which makes sense whilst still helping you go deeper into the content.
